Also check out our introduction covering the latest community-backed SBC trends from AI chips to the potential impact of tariffs (see link below).
Bulgaria-based Olimex’s OlinuXino project was among the first wave of hacker board projects along with BeagelBoard.org, Wandboard.org, and the Raspberry Pi community. Its aging A20-OlinuXino-Lime2 offers an Allwinner A20 with a Gigabit Ethernet (GbE, or 10/100/1000Mbps) port, microSD slot, HDMI port, LCD interface, and 3x USB ports. You also get battery support and 160 GPIOs. The 84 x 60mm SBC is available with Android 4.2.2 or Debian Jessie with Linux 3.4.1 mainline images.
The A20-OlinuXino-Micro, which recently dropped in price, has all the I/O of the first-gen Lime models, and adds audio I/O, VGA, and an LCD interface with touch support. This larger, 142 x 83mm board offers expansion connectors with optional I/O modules. Thereâs a choice of various flash options, and like all the OlinuXino board, optional -45 to 85Â°C support.
The 71 x 66mm A33-OlinuXino has a faster quad-core Allwinner A33 compared to earlier OlinuXino boards, but with a reduced feature set. The only real-world ports are a mini-USB OTG port, audio jacks, and a 5V jack. Two unassembled 40-pin connectors support GPIO, as well as 1280 x 800-pixel LCD and dual MIPI-CSI camera interfaces. You can download images for Android 4.4 and Armbian.
Compared to the beginning of the year, all the A64-OLinuXino configurations are now in stock and with lower prices. Like Olimexâs open source (Teres-A64) laptop, the 90.0 x 62.5mm A64-OLinuXino runs Ubuntu/Linaro on a quad Cortex-A53 Allwinner A64. The SBC is available in three models: a 1G0G version with 1GB RAM and no flash, a 1G4GW with 1GB RAM and 4GB eMMC, and a 2G16G-IND with 2GB RAM, 16GB eMMC and -45 to 85Â°C support. The 4GB model is the only one with WiFi and Bluetooth. All three A64-OLinuXino models offer GbE, microSD, USB 2.0 host, micro-USB OTG, HDMI, and MIPI-DSI connections. Thereâs also a 40-pin GPIO connector and an RTC with battery connector with step-up and charging support.
Just when we thought Arduino was done with its Linux experimentation, the company returned last year with a reboot of its original, MIPS-based Arduino Yun. It similarly combines a WiFi-enabled, 400MHz AR9331 SoC running OpenWrt Linux with an ATmega32U MCU that runs Arduino code. The board is again equipped with a microSD slot and USB host, micro-USB, and 10/100 Ethernet ports. Improvements have been made to the LAN and USB components, and you now get SSL support for improved security.
After a December unveiling by Team IoT, a project from Digital Loggers, Inc., the Atomic Pi went on sale this spring, quickly sold out, and is now back on sale at Ameridroid. It may also return soon to Amazon. Incredibly inexpensive for an Intel-based SBC — even considering its aging Cherry Trail design — the Atomic Pi is a modified version of Aaeonâs MF-001 SBC, which was used by Mayfield Robotics for its failed Kuri robot. According to a very negative Hackaday review, this is indeed a sell-off of old stock, although at 28,000 units, it might take a while. The 130 x 100 x 50mm SBC — the high profile is due to the heatsink — provides GbE, WiFi-ac, Bluetooth 4.0, USB 2.0, micro-USB 3.0 OTG, and an HD-only HDMI port with audio output. Thereâs also a 9-axis IMU, a debug interface, and a 26-pin GPIO connector with an optional $16 breakout board mounted on the bottom. Itâs pre-installed with Kubuntu (Linux Kernel 4.15) but can also run Windows 10. Although it wasnât clear at launch, the Atomic Pi is an open-spec board.
The Banana Pi BPI-M2 Berry is based on the earlier BPI-Ultra design, and similarly offers native SATA support. The Berry has a smaller, Raspberry Pi-like 85 x 56mm footprint and a different quad -A7 Allwinner SoC: the camera enabled Allwinner V40 in place of the almost identical R40. The SBC lacks the Ultraâs eMMC storage, and it offers 1GB DDR3 instead of 2GB. In place of a 5V jack, you use the micro-USB OTG, and you wonât find the Ultraâs battery support, IR, or debug UART. On the other hand, the Berry adds a fourth USB 2.0 host port and a MIPI-CSI connector. Other features include microSD, WiFi, Bluetooth, GbE, HDMI, MIPI-DSI, audio I/O, and an RPi-like 40-pin connector. This year, we seem to have lost one of the B2 spinoffs: The AliExpress page for the Allwinner A33 based Banana Pi BPI-M2 Magic says only to contact the supplier, but SinoVoip has no shopping page for it.
The Banana Pi BPI-M2 Ultra (BPI-M2U) can be found for $56 on AliExpress and $79 on Amazon. It upgrades the similarly 92 x 60mm BPI-M2 with a faster Allwinner R40 SoC that enables the Ultraâs native SATA connector. You get a generous 2GB of RAM, which is unusual for a Cortex-A7 SoC. The M2 Ultra is further equipped with GbE, WiFi, Bluetooth, 3x USB host, and single HDMI and micro-USB OTG ports. Other features include a 40-pin RPi connector, MIPI-DSI, an audio jack, and a mic interface.
Selling for $22.90 on AliExpress, the 60 x 30mm Banana Pi BPI-M2 Zero mimics the Raspberry Pi Zero W, but has a faster Allwinner H2+. The H2+ is like an Allwinner H3, but with HD instead of 4K support. The feature set is almost identical, with WiFi, BT, MIPI-CSI, 40-pin expansion, and mini-HDMI and power-only micro-USB OTG ports. There are two M2 Zero spinoffs: the BPI-P2 Zero, which adds 8GB eMMC and 10/100 Ethernet with PoE and the BPI-P2 Maker without the eMMC or WiFi (see below) They all run Ubuntu 16.04, Raspbian 9.4, and Android 4.4.
The Banana Pi M3 (BPI-M3) sells for $99 on Amazon with high-end features to match, starting with the octa-core Allwinner A83T SoC. The M3 has about the same size (92 x 60mm), layout, and features as the M2 Ultra, and similarly integrates a Pi-like 40-pin link. Like the M2 Ultra, the M3 supplies GbE, WiFi, SATA, 3x USB, and multiple display and camera options. Software support is more extensive than with some other Banana Pi boards, although all have improved. Choices include Android 5.1, Debian 8, Ubuntu 16.04 Mate, Raspbian Jesse Mate, and more.
SinoVoip’s only 64-bit Banana Pi sells for a low of $52 at AliExpress. The BPI-M64 provides 4K-ready HDMI, MIPI-DSI, and -CSI, as well as wireless and GbE connections. The 92 x 60mm board is further equipped with 3x USB host ports, a micro-USB OTG port, and an RPi 40-pin connector.
The BPI-P2 Zero, which is also available in a version without WiFi/BT or eMMC called the BPI-P2 Maker, was announced last August and began shipping earlier this year. The AliExpress page says the item is no longer available (for $28), and the only other shopping page we saw was on eBay ($34) plus $6 for the PoE option. This suggests the Zero may disappear soon. The stripped-down BPI-P2 Maker version, however, sells for $13.60 on AliExpress, or $18.70 with PoE. Otherwise, the features and software support are the same as the M2-Zero, which is itself a pseudo-clone of the RPi Zero W. The Banana Pi BPI-R64 SBC that was announced at the same time as the P2-Zero still hasnât reached market.
The BPI-R2 follow-on to the popular BPI-R1 router board was announced a year ago and is now shipping for $89.50 at AliExpress. Like the R1, the R2 offers 4x GbE ports and a WAN port, as well as HDMI 1.4 and MIPI-DSI outputs. The R2 has a faster, more network-capable quad -A7 MediaTek MT7623N SoC plus more RAM and storage and the option for a second SATA III interface. It also adds Bluetooth, mini-PCIe, 40-pin GPIO, and improved USB support: 2x USB 3.0 host and a micro-USB 2.0 OTG. The upcoming Banana Pi BPI-R64 will not be a clear upgrade. It offers a more network savvy, Cortex-A53 based MT7622 SoC, but thereâs no GPU and only two CPU cores. The BPI-R64 will have no video outputs and is limited to only 1GB of RAM and single USB and SATA connections. The BPI-R64 will have the same 148 x 100.5mm dimensions as the R1 and R2, and most of the same features of the R2.
The BPI-W2 router and NAS board , which sells for a low of $88 on AliExpress, is a spinoff of the BPI-R1 and R2 boards. The 148 x 100.5mm provides dual SATA III, dual GbE, and a WAN port. You also get 4x USB, including Type-C and 3.0 ports. For expansion there are 3x M.2 slots with PCIe support and a SIM slot, as well as 40-pin GPIO. Unlike most networking boards, the BPI-W2 can also bring it when it comes to multimedia: You get HDMI in and out, mini-DP, and an audio jack. The BPI-W2 runs Android 6.0, CentOS, Debian 9, Raspbian, Ubuntu 15.04, or OpenWrt on Realtekâs RTD1296, a NAS-oriented variant of the RTD1295 with a powerhouse Mali-T820 MP3 GPU. In February, SinoVoip announced a Banana Pi BPI-M4 with a quad -A53 Realtek RTD1395, but it has yet to reach market.
The industrial-oriented, Debian-ready BeagleBone Black Rev C stands out with its numerous expansion interfaces and programmable “PRU” MCUs, as well as its deeply rooted BeagleBoard.org community. This legendary hacker board is currently available for a low of $54 at Element14. The BB Black has been followed by more feature rich and/or lower cost clones, and it will soon be eclipsed by a roughly $100 BeagleBone AI. The upcoming AI model has a dual Cortex-A15 TI AM5729 SoC with AI support via dual C66x DSPs and 4x âEVEâ cores, as well as 1GB RAM, 16GB eMMC, WiFi, and GbE. Farther below, check two BeagleBone Green models from Seeed, as well as BeagleBoard.org’s own BeagleBone Black Wireless, BeagleBone Blue, and new PocketBeagle. Element14’s BeagleBone Black Industrial 4G, which is identical to the BB Black except for its conformal coating and -20 to 85Â°C support, is selling for $88.26 at AliExpress.
BeagleBoard.orgâs alternative to Seeed’s BeagleBone Green Wireless sells for a low of $65 on Arrow. Like the BB Green Wireless, the SBC adds 2.4GHz 802.11a/b/g/n and Bluetooth 4.1 BLE to the BeagleBone Black design. Unlike Seeed’s two BB Green models, the BeagleBone Black Wireless retains the BB Black’s micro-HDMI port, but removes the Ethernet port. It is otherwise identical to the BB Black with one big exception: It incorporates the OSD3358 SiP (system-in-package) module from Octavo Systems, which built the SBC as well. Octavo sells a more advanced OSD3358-SM-RED BeagleBone compatible with the same SiP package (see farther below).
This robotics-oriented, education-focused BeagleBoard.org collaboration with the UCSD Coordinated Robotics Lab is a BeagleBone clone that adds motion control and battery friendly power. The Blue has dropped to a new low of $68 at Arrow. Like the BeagleBone Black Wireless, the BeagleBone Blue integrates a TI WiLink 8 with WiFi and Bluetooth 4.1 LE, as well as an Octavo Systems OSD3358 SiP module that encapsulates the Sitara AM3358 SoC, RAM, and flash along with a PMIC and other features. There’s no Ethernet port or display interfaces, but you get micro-USB 2.0 host and client ports, 8x servo outputs, 4x DC motor outputs, and 4x quad encoder inputs. Other features include an IMU, barometer, JTAG, GPS, and DSM2 radio. You also get a 9-18V DC input, a LiPo battery connector, extra user buttons and LEDs, plus the usual extensive list of BB Black interfaces. Distro support includes the BeagleBoneâs default, real-time enhanced Debian stack, as well as Ubuntu Core, ROS, and ArduPilot.
Seeed’s BeagleBoard.org-sanctioned, IoT-focused re-spin of the BeagleBone Black lacks the BB Black’s micro-HDMI port and 5V barrel jack, but it costs less, and adds expansion connectors for Seeed’s Grove sensors. It also replaces the mini-USB port with a micro-USB.
The BeagleBone Green Wireless has the same base feature set as the BeagleBone Green, with identical additions and subtractions from the BB Black, including the addition of a Grove interface. The Wireless model adds WiFi and Bluetooth, as well as three more USB host ports for a total of four, making it the USB leader among all the BB Black clones. A TI WiLink8 module is now standard, boosting wireless capabilities to Bluetooth 4.1 LE and 2.4GHz 802.11a/b/g/n with 2×2 MIMO.
It doesnât cost much to try out the new C-SKY ISA launched in China by Hangzhou C-SKY. We can no longer find the companyâs C-SKY Linux Development Board, which debuts the Nationalchip GX6605S SoC selling on Taobao for $6, but we saw it for $15.90 on Tindie (from Maker go) and $18 to $20 on AliExpress (from Vector Trading Company). The C-SKY dev board is supported with a Linux 4.16 based stack with Buildroot and uClibc-NG, and ships with schematics. The SBC is a bit smaller than a Raspberry Pi and offers an HD-ready HDMI port and dual USB 2.0 ports. One of the two micro-USB ports supports JTAG debugging and the other offers 5V/1A power with UART console. A 5-pin header supplies power and 3x GPIO, and you get a reset button and several user buttons and LEDs.
Novtechâs 96Boards CE compatible Chameleon96 SBC is available for $155 at Arrow, up from $129 a year ago. The very first FPGA-based 96Boards entry runs Debian on a Cyclone V SE ARM/FPGA SoC. The Chameleon96 features SecureRFâs quantum-resistant security, as well as its Intel Video Suite for FPGA technology. The FPGA can stream 60fps 1080p video via the HDMI port, and can encode similar video via a two-lane MIPI-CSI camera interface. Other features include a microSD slot, a micro-USB OTG port, 2x USB 2.0 host ports, an audio interface, a USB Blaster, and a UART. Like most 96Boards SBCs, this 12V SBC offers WiFi and Bluetooth, but lacks Ethernet. It offers the usual 96Boards low- and high-speed I/O connectors.
The lone Linux board in the Arduino-oriented LittleBits maker platform is one of the smallest SBCs around at 15 x 10mm. The boardlet integrates WiFi, a power-only micro-USB port, and dual “BitSnap” connectors for adding standard LittleBits modules. The CloudBit is sold out at LittleBits, but a Cloudbit Starter Kit that offers the CloudBit with five prototyping modules is available elsewhere, with the lowest price at Walmart for $60. The Arch Linux based platform supports IFTTT scripting and connects to a Node.js-oriented cloud platform designed for monitoring IoT gizmos. This is the only board in our roundup with a SoC running the venerable ARM9 architecture.
Googleâs sandwich-style Coral Dev Board runs a Debian based Mendel Linux distro on a 48 x 40mm Coral SOM module equipped with NXPâs i.MX8M. The module showcases Googleâs Edge TPU chip, a stripped-down version of Googleâs TPU Unit for accelerating TensorFlow Lite AI models. The Edge TPU, which also appears in a Coral-branded USB stick and PCIe card, is backed up by a Cloud Edge IoT stack for cloud-integrated IoT edge computing and analytics. The Coral SOM offers 8GB eMMC and a rather paltry 1GB RAM, as well as a crypto chip and dual-band 802.11b/g/n/ac with BT 4.1 BLE. The 0 to 50Â°C tolerant Coral Dev Board has a somewhat Raspberry Pi like size and layout and offers a 40-pin GPIO connector. Ports include GbE, USB 3.0, USB Type-C OTG, USB Type-C 5V power, and micro-USB console. Media I/O includes a [email protected] HDMI 2.0a port, 4-lane MIPI-DSI and -CSI interfaces, and an audio jack and mic/speaker connections. Asus is prepping its own hacker boards based on the Coral SOM. The upcoming Tinker Edge T and more industrial CR1S-CM-A are loosely based on the Coral Dev Board.
The sandwich-style CubieAIO-S700 features the quad-A53 Actions S700 via CubieTechâs Einstein-S700 module, which integrates an Ampak AP6212 chip with WiFi-ac and BT 4.0. Aside from the different Einstein processor module, the board is a very close match in features and layout with the Allwinner A20 based CubieAIO-A20, which is now available only as part of a $127.90 touch-panel. The 170 x 106mm CubieAIO-S700 has a high, 20mm profile due to its 6x, double-stacked USB 2.0 host ports. The HDMI port tops out at HD resolution, but you get a GbE port, SPDIF audio, dual coastline serial ports, a SIM slot, and dual mini-PCIe slots, one of which has non-native mSATA. The CubieAIO-S700 also has a 54-pin expansion header, RTC, IR, and more. The full CubieAIO-S700 kit starts at $139 at AliExpress. Thereâs also a product page for an apparently sidelined CubieAIO-S500 SBC which is almost identical to the CubieAIO-S700 but has an Einstein S500 module with a quad -A9 Actions S500 SoC.
The CubieBoard4 is equipped with an octa-core Allwinner A80 SoC with a 64-core PowerVR G6230 GPU. The 111 x 111mm SBC offers WiFi, Bluetooth, and GbE, as well as VGA, HDMI, USB 3.0, and 4x USB 2.0 ports. There’s also a 54-pin expansion connector. The SBC provides optional configurations including dual microSD slots or a mix of microSD and onboard flash. There are plenty of cases and other add-ons, as well as images for Debian, Ubuntu, and Android, with mainline Linux support. The board costs $117 on AliExpress and $129.90 at Amazon.
The CubieBoard5, which sells for $109 at Amazon, showcases an Allwinner H8 with eight Cortex-A7 cores. The SBC provides microSD and SATA storage, with an optional RAID add-on board. For connectivity, you get WiFi, Bluetooth 4.0, and a GbE port. Dual display support is available via the HDMI and DisplayPorts. The board is further equipped with a pair of USB host ports, an IR sensor, SPDIF audio, and an optional lithium battery.
The CubieBoard6 and CubieBoard7 SBCs, which are identical except for their processors, are the fully integrated SBC cousins to the sandwich-style CubieAIO-S500 and CubieAIO-S700, respectively. These updates to the four-year old CubieBoard2 have smaller 100 x 60mm footprints compared to the CubieAIO boards, as well as a reduced feature set. The key advantage in addition to their lower prices is that their non-native SATA ports piggyback on a faster USB 3.0 connection to offer an approximation of SATA III. The boards provide 10/100 Ethernet, 802.11n, and BT 4.0, as well as 2x USB 2.0 host ports and a mini-USB port. Other features include HD-ready HDMI, audio jacks, RTC, IR, a UART header, and dual 48-pin GPIO headers. Like the CubieAIO boards, they are supported with Actions-optimized Android 5.1.1 and Debian builds. The CubieBoard6 sells for $89 and the CubieBoard7 for $99, both at AliExpress. Last year, CubieTech posted a product page for a quad -A53 Actions S900 based CubieBoard9 replacement for the CubieBoard4, but it has yet to reach market.
The DE0-Nano-SoC Development Kit looks like a commercial development board, but it offers open specifications and is supported on the RocketBoards.org community site. The DE0-Nano-SoC uses the lower-end SE variety of Intelâs Cyclone V SoC, which is roughly equivalent to a Xilinx Zynq-7020. The SoC similarly combines FPGA circuitry with dual Cortex-A9 cores running Angstrom v2014.12 Yocto 1.7 with a Linux 4.0 kernel. The board has GbE, USB OTG, and micro-USB ports, as well as a microSD slot with a 4GB data card. There’s also an accelerometer, an Arm-linked expansion header, and a variety of FPGA-linked interfaces, including a 40-pin header and an Arduino shield connector.
The Qualcomm-backed DragonBoard 410c and the now defunct HiKey were the first 96Boards Consumer Edition (CE) SBCs as well as the first 64-bit ARM hacker SBCs. The 85 x 54mm, Snapdragon 410 driven SBC lacks an Ethernet port, but you get WiFi, Bluetooth, GPS, HDMI, microSD, 3x USB ports, and the 96Boards 40-pin low-speed and 60-pin high-speed connectors. The SBC supports Android 5.1, Debian 8.0, and Windows 10 IoT Core. Meanwhile, Arrowâs newer DragonBoard 820c CE Extended SBC based on the high-end Snapdragon 820E has disappeared, at least temporarily. Earlier this year, Arrow announced three 96Boards CE Extended SBCs that have yet to reach market. These include the Avenger96 equipped with STâs new Cortex -A7/M4 hybrid STM32MP1 SoC, as well as the AI-ML Board and Thor96 which run Linux on NXPâs i.MX8X and i.MX8M SoCs, respectively. ST is prepping its own low cost, and possibly open-spec, dev boards for the STM32MP1, including the $69 STM32MP157A-DK1.
Late last year, Bitmain, which is known for its bitcoin mining systems, launched an open-spec, 96Boards CE compatible SBC to show off its 1-TOP âBM1880 TPUâ for deep learning applications. The boardâs $129 shopping page indicates the board is âcoming soon,â with a name switch from the original Sophon BM1880 EDB (Sophon Edge) to the Edge TPU Developer Board. Almost as confusing as the name — as far as we know this has nothing to do with Googleâs Edge TPU AI chip — it appears the board as already shipped, judging by this eBay listing selling the board in ânewâ condition for an inflated $199. The BM1180 SoCâs TPU is accompanied by dual Cortex-A53 cores running Linux, as well as a RISC-V companion MCU. Although this headless, Raspberry Pi sized board offers only the 96Boards 40-pin connector, not the 60-pin interface, 96Boards.org lists it as an official 96Boards offering. Raspberry Pi and Arduino add-on modules are optional. Other features include GbE, micro-USB UART debug, and 3x USB 3.0 host/OTG ports. You also get a microSD slot, JTAG, and USB-based WiFi/BT.
This low-end Firefly board has long been available at a $60 promotional price. The Firefly-RK3128 dual boots Android 5.1 and Ubuntu 15.04 on a quad-core -A7 Rockchip that is clocked slower than the RK3288 and offers half the RAM and flash of the Firefly-RK3288. The sandwich-style, COM/baseboard device includes GbE, WiFi, BT, HDMI, MIPI-DSI, MIPI-CSI, SPDIF, analog audio, LVDS, IR, and CVBS. The 117 x 85mm board is further equipped with 4x USB host ports, a micro-USB OTG port, and dual 42-pin expansion connectors. A year ago, Firefly introduced a similar, but extended temp SBC called the Firefly-PX3-SE. However, this sandwich-style board with a Core-PX3-SEJ module featuring a quad -A7 Rockchip PX3-SE is out of stock, and Firefly has yet to post any schematics or other open source resources, so weâve removed it. Resources for Fireflyâs other open source boards may be found on the download page.
Starting at $119, this 118 x 85mm SBC dual boots Ubuntu 14.04 and Android 4.4 with mainline Linux 4.4 support on a 1.8GHz, quad -A17 RK3288 with Mali-T760 GPU. The Firefly-RK3288 has an HDMI 2.0 port that can output at up to 4Kx2K @ 60Hz. The board offers dual-band 802.11ac, Bluetooth 4.0, a GbE port, and 3x USB ports, and is further equipped with VGA, LVDS, eDP, MIPI-DSI, MIPI-CSI, SPDIF, serial debug, and IR connections. More I/O is available via dual 42-pin connectors. Options include a “Fireasy” WiFi remote, touchscreens, fans, and cameras. The sandwich-style Firefly-RK3288 Reload SBC is out of stock and no longer listed.
The original Rockchip RK3399 hacker board starts at $149, and a Firefly-RK3399 Max version with 128GB eMMC goes for $259. Both models provide a microSD slot and an M.2 slot that can be used for an SSD. Other features include a GbE port, WiFi-ac, Bluetooth 4.1 BLE, a SIM card slot, and a mini-PCIe slot that can load an optional LTE module. DP and HDMI ports drive up to 4K @ 60Hz video, and you get MIPI-DSI, eDP, DVP, IR, and 2x MIPI-CSI. The Firefly-RK3399 offers 2x USB 3.0 ports (including a Type-C), 2x USB 2.0 ports, a 42-pin expansion header, and numerous audio options. The board dual-boots Android 6.0.1 and Ubuntu 16.04. Firefly also sells an RK3399 Coreboard COM version of the Firefly-RK3399. The CoreBoard is now available in a sandwich-style AIO-3399J board, which sells for $165.
The Firefly-ROC-RK3328-CC is the Firefly branded version of Libre Computerâs Renegade SBC, which launched on Indiegogo in 2017. Like Pine64âs Rock64 SBC, this is an RK3328-based Raspberry Pi clone with an RPi 3-like footprint, layout, and 40-pin interface, as well as very similar features. The main differences from the Raspberry Pi 3 include the lack of WiFi, Bluetooth, and MIPI-CSI and -DSI, as well as the presence of 3x USB host ports (one of them 3.0) instead of four. Like the Rock64, you get GbE instead of 10/100 Ethernet, and HDMI 2.0 with 4K instead of an HD-only HDMI 1.4. Firefly and Bay Libre assisted Libre Computers with software support, which includes Android 7.1 and Ubuntu 16.04, with the latter offering a choice of Rockchipâs Linux 4.4 Kernel and Mainline Linux 4.14 LTS.
Arriving at the end of 2018, the HummingBoard CBi (CAN bus interface) is an even more industrial variant of the HummingBoard Edge (see below) that swaps the HDMI port and GPIO for CAN and RS485 ports. It also comes standard with Edge options including an enclosure, heatsink, WiFi/BT, and -40 to 85Â°C support. It has the same footprint as the Edge and similarly runs Linux on a choice of dual- or quad-core i.MX6 based MicroSOM modules. Debian, Yocto, Buildroot, and OpenWrt stacks are available with Linux 4.4x. Except for an extra user button and LEDs, the board is identical to the Edge. The 2GB Dual version is described in the LG link above, and the 4GB Quad version may be found here.
Like all the HummingBoards except for the sandwich-style, but i.MX8M based, HummingBoard Pulse, the HummingBoard Edge incorporates i.MX6 based MicroSOM modules. In Oct. 2016, SolidRun revised the HummingBoard MicroSOM COMs, which can also be bought separately. More recently, all the Edge SKUs have begun shipping with 8GB eMMC, up from the 4GB that some models were limited to. The 102 x 69mm HummingBoard Edge duplicates all the features of the smaller HummingBoard Pro and doubles the USB 2.0 count to four. It also adds M.2, SIM, and MIPI-DSI connections, provides a larger 36-pin GPIO connector, and boosts the power supply to a wide-range 7-36V. As with the Pro, there are numerous options including wireless modules. Extended and industrial temp versions are also available. See above for the Edge-like HummingBoard CBi, which adds CAN and serial ports.
As the name suggests, the HummingBoard Gate is designed primarily for IoT gateway duty. The SBC is almost identical to the HummingBoard Edge, with the same 102 x 69mm footprint, 7-36V power supply, mini-PCIe slot, and optional wireless modules and metal enclosure. However, it lacks Edge features like LVDS, analog audio, or eMMC and M.2 storage. It also adds a MikroBus socket that accepts MikroElektronika’s 200-plus Click add-on I/O and sensor modules. Multiple temperature ranges are available, and like the Edge models, they all ship standard with 8GB eMMC.
The HummingBoard Pro is an updated version of the HummingBoard Base, which is now available only by special order. The Pro is identical to the Base except that it adds mini-PCIe, mSATA, LVDS, analog audio, RTC, and IR. It also offers two more internal USB headers. Options on both models include microSD slots, a wireless module, a power adapter, and a custom enclosure. Like the other HummingBoards, it now ships standard with 8GB eMMC.
The Pulse advances to NXPâs 64-bit i.MX8M SoC via i.MX8 SOM modules available in Dual or Quad versions. Only the lowest $182 configuration with an i.MX8M Dual, no wireless, and commercial temp support falls under our $200 limit. The HummingBoard Pulse is a bit larger than the first-gen HummingBoards at 102 x 69mm, and it replaces the GPIO in favor of single mini-PCIe, M.2, and SIM slots. Like the HummingBoard Gate, it provides a Mikrobus connector for adding Click modules. The Pulse is notable for its dual GbE ports, and offers 2x USB 3.0, USB Type-C, and HDMI 2.0 ports. You also get an RTC, IR receiver, 7-36V input, a heatsink, and an optional metal enclosure. Note that you will soon be able to buy the Pulse with a new i.MX 8M Mini module that offers an i.MX8M Mini instead of the i.MX8M. The module adds a Gyrfalcon neural accelerator.
The Khadas Edge was announced in July 2018 and launched on Indiegogo in November along with a similar Edge-V model and an RK3399Pro based Edge-1S. The Edge and Edge-V were promised for January shipment, but have been delayed. A May 14 update says the PCBs have arrived at the factory, and the Khadas shopping page has pre-order pages for the Edge and Edge-V and an order page for the optional, $45 Captain Carrier. The Edge has an MXM3 connector for deploying it like a compute module onto a cluster or carrier board such as the gaming-oriented Captain Carrier. It also offers FPC connectors for hooking up options like the Edge IO serial debug and GPIO board. The Edge-V replaces the MXM3 and FPC links with a Khadas Vim-like 40-pin RPi connector and adds a GbE port, microSD slot, and M.2 2280 socket with NVMe support. The Edge-V also adds MIPI-CSI and -DSI, eDP 1.3, touch support, RTC, IR, gesture sensor module, and 6-axis IMU. The still unavailable Edge-1S is identical to the Edge, but adds a GbE port and advances to Rockchipâs RK3399Pro with a 3-TOPS NPU. Features found on all three RPi-sized Edge models include single USB 3.0 and 2.0 ports and 4K-ready DP and HDMI 2.0a, with the DisplayPort available via one of the two USB Type-C ports. Basic models (2GB/16GB) offer dual-band WiFi-ac and BT 4.1 while the Pro and Max boost the Bluetooth to 5.0 and add RSDB WiFi. Thereâs a wide-range DC input and support for âAndroid N, P, Ubuntu Mate.â
The original Khadas Vim board was followed by a Vim2 model, which will soon take back seat to an upcoming Vim3. The 82 x 58mm Vim1 uses an Amlogic S905X, a lower-cost upgrade to the quad-core, -A53 Amlogic S905 found on the Odroid-C2. OS support includes Android 6.0 with Kodi-17, as well as Ubuntu 16.04, Buildroot, and 7.0 versions of the Kodi-oriented OpenELEC/LibreELEC. The Vim1 offers 802.11ac WiFi, Bluetooth 4.2, Fast Ethernet, and 3x USB 2.0 host ports, one of which is a Type-C OTG with power support. Other features include HDMI 2.0a, IR, microSD, and 40-pin expansion. Shenzhen Wesionâs Khadas project also offers a $99.90 Khadas Tone Board audio add-on for the Vim boards.
The Khadas Vim2 Pro and Max models with additional eMMC are not currently available, although a note suggests that the Max may be back. The Vim2 has the same 82 x 58mm footprint as the Vim1, but advances to an octa-core Amlogic S912 and Mali-T820 GPU. Software support is similar except that the Vim2 moves to Android 7.1. Like the original, the board is equipped with HDMI 2.0a with [email protected] decoding, 2x USB 2.0, a micro-USB OTG Type-C with 5V input, and a 40-pin expansion connector. The Vim2 advances to GbE with WoL and adds an FPC link and two Pogo Pad I/O connectors, one of which controls an STM8S003 MCU for a programmable EEPROM. Other features include microSD, RTC, IR, and an acrylic case. With the recent announcement of the Khadas Vim3, which features a faster Amlogic S922X with 4x -A73 and 2x -A53 cores, Khadas has reduced the price of the Khadas Vim2 to $99.90. Update: shortly after publication, CNXSoft reported that the Vim3 will go on sale June 24 for a very competitive $70 (2GB/16GB) or $90 (4GB/32GB), although prices will increase on July 22.
8devices, which is known for MIPS-based modules such as the Carambola, has released an open-spec Komikan DVK board that features a not-so-open Komikan compute module. The module runs OpenWrt on a MIPS-based Realtek RTL819FS SoC accompanied by a Realtek RTL8822BEH chipset with Wave 2 WiFi and BT 4.1. Wave 2 provides concurrent 2.4GHz/5GHz, MU-MIMO 802.11a/b/g/n/ac for up to 1.166Gbps throughput. Unlike most Wave 2 devices, the Komikan can operate without a heatsink with low 6W consumption. The Komikan DVK adds an eMMC socket, microSD slot, 10/100 and 10/100/1000Mbps ports, 2x USB 2.0 ports, and a USB Type-C for power and console duty. You also get antennas and a 20-pin GPIO.
In October, Libre Computer launched its La Frite (AML-S805X-AC) on Kickstarter and hit several stretch goals. Shipments are way late and backers are upset that the latest update was back on Jan 4. Nevertheless, LoverPi has a pre-order page with prices at least twice as high as on KS. La Frite is a smaller, stripped-down version of Le Potato (AML-S905X-CC) and is billed as a replacement for the Raspberry Pi Model A+. Since it launched, an improved, $25 RPi 3 Model A+ arrived, which Libre Computer compares to La Frite in a December update post. La Frite has a lower-powered, 1.2GHz S805X compared to the 1.5GHz S905X model found on Le Potato. Coastline ports include a low-profile 10/100 Ethernet, an HD-ready HDMI, 2x USB 2.0, and a micro-USB OTG port with power input. Thereâs also an RPi-style 40-pin header, an IR receiver, and a boot button. The board supports mainline Linux with Ubuntu, Debian, LibreELEC, Lakka, RetroPie, Android Oreo, and more.
LeMaker’s sandwich-style Guitar SBC integrates a COM with a quad-core Actions S500. Images are available for Android 5.0, Ubuntu Mate, Ubuntu Core, Lemuntu, Armbian, ArchLinux, and a LeMaker XBMC (Kodi) media playing variant called LeMedia. The 88 x 81mm baseboard offers WiFi, Bluetooth, Ethernet, HDMI, micro-USB 3.0, and dual USB host ports. There’s also a MIPI-CSI interface and an RPi-compatible 40-pin connector.
After supplying its Kickstarter backers with the Raspberry Pi-like Le Potato, Libre Computer is selling the SBC at LoverPi as the Libre Computer Board (AML-S905X-CC). Itâs equipped with the same quad -A53 S905X SoC found on the original Khadas Vim, and has the same size, port layout, and basic feature set as the Raspberry Pi 3, including 4x USB host ports, Fast Ethernet, and 40-pin expansion. Thereâs no WiFi/BT, but you get optional eMMC, IR, and an ADC + I2S header. The HDMI port is upgraded to 2.0 with 4K. The board ships with schematics and source code for Linux 4.14 LTS, Buildroot with Linux 4.9, Armbian Debian and Ubuntu, LibreELEC 9, and Android builds up to 8.0 (Oreo). Libre also launched a La Frite board thatâs like a stripped-down Le Potato and created an RPi-like Renegade SBC with a Rockchip RK3388 that is sold by Firefly as the Firefly-ROC-RK3328-CC (see above). In addition, the company has launched an RK3399 based Libre Computer Board ROC-RK3399-PC (Renegade Elite) and an Allwinner H2+/H3 based RPi clone called the Tritium (see below).
Last August, a startup founded by former Allwinner employees launched an open-spec, 139 x 85mm SBC that debuts a 1.5GHz Allwinner camera SoC called the V5 V100. Instead of the usual Mali GPU, the SoC offers a custom VPU, a dual-core ISP, and an âAIEâ acceleration engine for visual analytics. The Lindenis V5 runs Linux 4.4, as well as a homegrown Debian 9 stack called Linbian that supports the V5 V100 SoC and its AIE engine with OpenCV, Compute Library, Tensorflow, and GStreamer with hardware acceleration. Taobao has the lowest, $87 and up price and non-Chinese buyers can more easily purchase it for $95 at AliExpress. Features include GbE and 4K-ready HDMI ports, 4x USB 2.0, and a micro-USB port. You also get 2x MIPI-CSI2 interfaces with an optional camera module, plus MIPI-DSI, audio, mic, microSD, optional WiFi/Bluetooth, and an RPi 40-pin header.
MediaTek Labs’ miniscule, Seeed-built LinkIt boards run OpenWrt on a 580MHz MIPS SoC, and target IoT endpoints and gateways. The $15 model measures 56 x 26mm, and offers WiFi, microSD, and dual micro-USB ports, while the $18, 61 x 26mm LinkIt Smart 7688 Duo adds an MPU for Arduino support. The boards provide GPIO, I2C, SPI, UART, PWM, and Fast Ethernet, plus I2S audio on the base model and ADC and SPI on the Duo. Seeed offers an optional breakout board for the standard LinkIt and provides three options for the Duo: breakouts for Arduino and Grove sensors and a more feature-rich Grove Starter Kit.
The LinkSprite Acadia runs Ubuntu 12.04 or Android 4.4 on an i.MX6 Quad. Compared to the V2 model covered in our original report linked to above, the V3 loses the onboard eMMC flash but furnishes both a microSD slot and dual SD slots. Other features include HDMI, LVDS, SATA, audio, and GbE, as well as three USB ports, dual cameras interfaces, and an Arduino-compatible header.
The LinkSprite Arches was unveiled as the pcDuino8 in May 2014, and then arrived in beta form later in the year with its current name before going final in 2015. The Arches runs Linux or Android on an octa-core Allwinner A80 and is configured much like the A80-based Cubieboard4. The SBC is equipped with microSD, HDMI, GbE, and three USB ports (one of them 3.0 OTG), as well as WiFi, Bluetooth, and a CSI interface.
Built by Silicom (formerly ADI Engineering), with the support of the Intel-backed MinnowBoard.org community, the 3.9 x 2.9-inch MinnowBoard Turbot Dual (MBT-2210) replaced the CircuitCo-built MinnowBoard Max. Thereâs also a MinnowBoard Turbo Quad-core (see item below). This may be our last posting for the aging SBC, which is available for a low of $160 at Mouser. The short-lived Dual-Ethernet (Dual-E) model is no longer available. The Dual board includes a low-speed expansion header that provides Arduino-like prototyping I/O, as well as a 60-pin high speed connector for add-on boards called Lures. Other I/O includes dual USB ports plus GbE, micro-HDMI, and SATA. Firmware support includes Debian, Ubuntu, Yocto Project, Android 4.4, and Windows 10.
The MinnowBoard Turbo Quad-core, which began shipping in 2017, has the same 99 x 74mm footprint as the dual-core Turbot Dual, and much the same layout and feature set. The Quad advances to the quad-core, 1.91GHz Atom E3845 from the same 22nm Bay Trail generation, and adds a heatsink, a fan, and a faster GbE controller. As with the Turbo Dual, ADI (now called Silicom) launched a Dual-Ethernet model that is now defunct. A previously teased, Apollo Lake MinnowBoard 3 is over two years late. The Minnowboard project appears to be heading for the exits.
MYIR is primarily a commercial board vendor, but it has spun several open-spec hacker boards like the MYS-6ULX SBC that have crossover appeal to makers. Others include the Sitara-based Rico Board and Zynq-based Z-turn boards (see farther below). The MYS-6ULX offers a choice of i.MX6 UL (UltraLite) or its very similar sibling, the i.MX6 ULL. Each SBC model has its own unique super-power: The i.MX6 UL version offers -40 to 85Â°C support instead of 0 to 70Â°C, and the i.MX6 ULL model features a USB-powered WiFi radio. Otherwise, the 70 x 55mm boards are identical. You get a microSD slot, Fast Ethernet, USB host, and micro-USB 2.0 OTG ports, as well as a debug connector and an LCD interface for optional touchscreens. The dual 20-pin expansion connectors can be used to attach an optional baseboard. The MYS-6ULX comes with a Linux BSP with a 4.1.15 kernel and either Debian or Yocto Project with Qt. There’s no forum or dedicated community site, but you get full schematics, support, and extensive documentation.
FriendlyElec (AKA FriendlyARM) is known for its many NanoPi SBCs, but it also offers some more feature-rich NanoPC models. The NanoPC-T3 Plus replaced the NanoPC-T3, and is similarly equipped with an octa-core S5P6818. The earlier, almost identical NanoPC-T2 with a quad-core S5P4418 is still available for $49). The T3 Plus doubles the RAM and flash of the T3 and adds -40 to 80Â°C support. Itâs slightly larger at 100 x 64mm, and switches one of the USB headers to a Type-A port so there are 3x coastline USB 2.0 host ports instead of two. Like the T3, the T3 Plus supplies WiFi, BT 4.0, and a GbE port, as well as microSD and micro-USB client connections. Media ports include HDMI, LVDS, LCD, MIPI-DSI, MIPI-CSI, and audio. In place of the 40-pin RPi connector found on NanoPi boards, the NanoPC-T3 Plus provides a 30-pin GPIO header. OS support includes Android, Debian, and the Ubuntu Core 16.04 based FriendlyCore. Available images for each of FriendlyElecâs boards may be found here.
When it debuted in early 2018, the 100 x 64mm NanoPC-T4 was the smallest RK3399 SBC around, an honor that in the summer fell briefly to FriendlyElecâs Raspberry Pi like NanoPi M4 and in the fall to the smaller, 1GB RAM only NanoPi Neo4 (see below). The relatively high price is due to a standard allotment of 4GB of RAM. FriendlyElecâs first Rockchip-based SBC is also its most powerful, combining the hexa-core RK3399 with advanced features like M.2 and native SATA. Display interfaces include HDMI 2.0, DP, eDP, and MIPI-DSI. You also get MIPI-CSI with dual-camera support, an RPi-compatible 40-pin interface, and a 0 to 80Â°C operating range. OS support includes Android 8, Lubuntu Xenial, and the similarly Ubuntu based FriendlyCore and FriendlyDesktop Bionic.
FriendlyElec’s NanoPi A64 has a 64 x 60mm footprint that matches the NanoPi M3. The A64 provides two USB host ports, a power-only micro-USB, and HDMI, MIPI-DSI, microSD, audio, and DVP camera connections. The 5V SBC offers GbE and WiFi, but no Bluetooth, and you get the NanoPi-typical 40-pin RPi header. Images are available for FriendlyCore Xenial and Ubuntu Mate. Like most of the NanoPi and NanoPC SBCs boards, the NanoPi A64 is available with a growing list of options ranging from cases to heat sinks to camera modules. Also like its siblings, the price is insanely cheap, but shipping to the U.S. is fairly expensive — single-unit prices range from $16 to $20, compared to under $4 for Orange Pi boards.
The tiny (50 x 25.4mm) NanoPi Duo was launched in Aug. 2017 as the first of several headless, COM-like NanoPi boards, including the more recent, 40 x 40mm NanoPi Neo Core and Core2 spins of the Neo and Neo2. The $13 to $15 Duo is now out of stock, apparently replaced by last yearâs new NanoPi Duo2, which switches the HD-ready Allwinner H2+ to the similar, but 4K ready, H3 model. The NanoPi Duo2 also provides an optional new IoT-2G Application Carrier Board that replaces the Duoâs optional Mini Shield carrier. The only other differences include the addition of Bluetooth and a narrower -20 to 70Â°C range. The Duo2 has 32x I/O pins via a dual-in-line interface designed to plug into the IoT-2G carrier or a 2.55mm pitch breadboard. Unlike the Core boards, the Duo2 supplies WiFi, a microSD slot, and a micro-USB port, qualifying them as standalone SBCs. The SBCs supply headers for 10/100 Ethernet, 2x USB host, audio, CVBS, and serial debug. The 85 x 56mm IoT-2G carrier is sized like a Raspberry Pi but is limited to dual USB 2.0 host ports. The board has quad-band, 2G GSM/GPRS module and microSIM slot, as well as a 2G antenna. The NanoPi Duo2 is available with FriendlyCore 16.04 Xenial and OpenWrt.
In April 2018, FriendlyElec engineered a spinoff of the $39, but now out of stock NanoPi K2. The new NanoPi K1 Plus switches from the K2âs Amlogic S905 to a similarly quad -A53 Allwinner H5 SoC and swaps out the WiFi/Bluetooth for a 2.4GHz WiFi-only module. It also demotes the HDMI 2.0 port to an HDMI 1.4 port with 4K video throttled back to 30fps. The K1 Plus subtracts one of the USB 2.0 host ports, leaving 3x USB 2.0 ports total along with a micro-USB OTG port with power input that fills in for the removed DC-in jack. It also adds a DVP camera interface, a mic, and a 3.5mm audio jack that outputs CVBS signals. Other features are the same, including the 2GB RAM, microSD slot, eMMC socket, and GbE port. You also get an IR receiver, a heatsink, a debug header, and a 40-pin connector.
This more feature-rich update of the discontinued NanoPi M1 retains the Allwinner H3 but is slightly smaller at 64 x 60mm. The higher price of the NanoPi M1 Plus reflects the standard 1GB RAM and 8GB eMMC, as well as new features like WiFi, Bluetooth, a mic, and Gigabit Ethernet. One of the three USB 2.0 host ports, however, has moved to an onboard header. Other features include HDMI, DVP camera, CVBS A/V, IR, and a microSD slot, plus a 40-pin RPi header. OS options include FriendlyCore Xenial, OpenWrt, and Debian.
Of the three RK3399 based SBCs released by FriendlyElec in 2018, the NanoPi-M4 may be the âjust rightâ tradeoff. You get a choice of 2GB or 4GB RAM instead of being limited to 1GB with the smaller, $45 NanoPi Neo4 or 4GB with the larger, $110 NanoPC-T4. Unlike the NanoPC-T4, the NanoPC-M4 has a Raspberry Pi form factor, layout and 40-pin header. It also has a 24-pin header with 2x PCIe lanes. Other features include native GbE, 802.11ac, Bluetooth, HDMI 2.0a, USB Type-C, and 4x USB 3.0 ports. You also get audio I/O, an RTC, -20 to 70Â°C support, and two configurable MIPI-DSI/CSI interfaces. OS support includes Android 7.1.2 Lubuntu 16.04, FriendlyCore 18.04, and FriendlyDesktop 18.04.
In Nov. 2017, FriendlyElec replaced its NanoPi 2 Fire with two fiery new models: a $35 NanoPi Fire3 with an octa-core S5P6818 and 1GB RAM and a $28 NanoPi Fire2A with the same quad -A9 S5P4418 found on the defunct NanoPi 2 Fire. The two boards are otherwise identical, but unless youâre buying in volume, the only reason we can see to choose the slower NanoPi Fire2A is to save on power. FriendlyElec has now added âLTSâ to the name of the Fire3 to indicate it is a long-term support model. The chief differences between the new Fire3 and earlier 2 Fire include a realignment of the USB 2.0 port into a vertical position, and the replacement of the HDMI port with a micro-HDMI, enabling it to sit side-by-side with the GbE and USB ports. You also get a microSD slot plus RGB LCD, DVP camera, serial debug, and a RPi 40-pin interface. The 5V board is powered by a micro-USB OTG, and thereâs an RTC with battery and PMIC. The 75 x 40mm Fire3 runs Android 5.0 and Linux distros including FriendlyCore. With the discontinuation of the NanoPi M2A, this is the only Samsung-driven NanoPi around. The Fire3 is also part of a 12-board, 96-core compute cluster.
The Neo was the first of a sub-series of tiny NanoPi boards such as the wireless enabled Neo Air, quad -A53 Neo2-LTS, and the Neo Plus2 (see below). The Neo boards are among the world’s smallest and most affordable quad-core ARM SBCs. At 40 x 40mm, they occupy only 1,600 square millimeters, compared to 1,950 sq. mm for the 65 x 30mm Raspberry Pi Zero. The NanoPi Neo, which has now been given LTS status, is equipped with microSD, USB 2.0 host, and micro-USB OTG ports, but like the other Neo variants, it lacks a display interface. You get 36 GPIO pins instead of the usual RPi connector. The board runs Ubuntu Core or Mate on the Allwinner H3.
In early 2017, the quad -A7, 40 x 40mm NanoPi Neo was joined by a 64-bit quad -A53 near twin called the NanoPi Neo2. The Neo2 was updated with a v1.1 model that added a 1GB RAM option, and itâs now referred to as the Neo2-LTS (for long-term support). The Neo2 is the same as the Neo except for the faster H5 SoC, a switch to GbE from 10/100 Ethernet, two more USB headers, and the lack of a 256MB RAM option. In Dec. 2017, FriendlyElec launched COM versions of the Neo and Neo2 called the NanoPi Neo Core ($8) and NanoPi Neo Core2 ($25), which are designed to work with an optional, $11, RPi-like Mini Shield carrier board. The sandwich-style design is much like the NanoPi Duo and its own Mini Shield variant except that the Core boards are true COMs rather than SBCs.
When it launched in Oct. 2018, the $50 Neo4 was the worldâs smallest, cheapest RK3399 based SBC, and although the Rock Pi 4 has since edge it out on price, itâs still the puniest. Although rich with features, it offers only 1GB of RAM, which is likely insufficient for the high-powered RK3399 SoC. At 60 x 45mm, the SBC is larger than other Neo boards, which lack its HDMI 2.0a port with [email protected] support and 4-lane MIPI-CSI. Other features include GbE, USB 3.0, and USB 2.0 ports, a USB Type-C power and OTG port, and a USB 2.0 header. You also get WiFi/BT, a 40-pin header, and -20 to 70Â°C support. From the microSD slot or eMMC socket (add $12 for 16GB), you can boot Linux 4.4 LTS, Lubuntu 16.04, FriendlyCore 18.04, FriendlyDesktop 18.04, Armbian, and Android 7.1.2 or 8.1. FriendlyElec also offers sells two other RK3399 SBCs: the high-end, SATA-ready NanoPC T4 and the mid-range, RPi style NanoPi M4.
The NanoPi Neo Air-LTS is a wireless variant of the NanoPi Neo. This headless IoT board has the same 40 x 40mm footprint, and similarly runs Ubuntu Core and Mate on an Allwinner H3. The Neo Air comes standard with 512MB of RAM, and adds WiFi, Bluetooth 4.0, and a DVP camera connector. You also get 8GB to 32GB eMMC. The Air sacrifices the Neoâs Ethernet port and the sole USB host port, however, leaving you only a micro-USB OTG for power and data. You can derive more USB ports or a power connection via the split bank of 36 GPIO pins. The board was recently designated as LTS (long-term support).
The NanoPi Neo Plus2 SBC combines the WiFi, Bluetooth 4.0, and 8GB eMMC of the Neo Air with the quad -A53 Allwinner H5 of the Neo2. It also boosts RAM to 1GB, although thereâs a new 512MB option as well. Itâs not a Neo drop-in replacement, however, as the dimensions have grown to 52 x 40mm. Like the other Neo boards, the SBC offers a bootable microSD slot, GbE port, dual USB 2.0 ports, and a micro-USB for 5V power. As before, you get serial debug and audio interfaces, as well as two banks of expansion connectors: a high-speed 12-pin interface and a 24-pin low-speed connector. A $7, I2C-driven NanoHAT OLED display add-on with 128 x 64-pixel resolution ships with an open source driver and NanoHAT Motor Python Library. The add-on can be stacked on any of the Neo boards, with the combo housed in an optional aluminum casing.
The R1 is yet another Allwinner H3 based NanoPi, but this time with a twist: a pair of Ethernet ports (GbE and Fast) and an 802.11n/Bluetooth 4.0 module for gateway networking duty. The tiny (60 x 55.5mm), headless SBC runs FriendlyCore with Linux-4.14-LTS or OpenWrt on the quad -A7 SoC. Other R1 features include dual USB 2.0 host ports, micro-USB power port, -20 to 70Â°C support, an RTC, and a standard metal case with external antenna. Itâs most closely comparable with the slightly smaller, H2+ based Banana Pi BPI-W2 with dual 10/100Mbps ports.
The Nitrogen8M_Mini features NXPâs new i.MX8M Mini SoC, which is faster than an i.MX8M, but is limited to HD video. The 114.3 x 88.9mm board offers a choice of pre-certified WiFi-ac/BT with or without a dev kit, which includes a 5V power supply, an 8GB microSD card with Linux, a battery, and a serial console cable. The standard SKU includes a GbE port with optional PoE. USB ports are limited to single USB 2.0 and micro-USB OTG ports, but you get MIPI-DSI and -CSI, with the latter available with an optional 5MP camera. The SBC offers dual audio jacks, a PCIe slot, an RTC, a PMIC, and a choice of 0 to 70Â°C or -40 to 85Â°C operation. OS support starts with Linux kernel 4.9x and includes Yocto, Ubuntu 18.04, Debian Stretch 9.5, Android 8.1. Boundary Devices also sells a more expensive, sandwich-style offering based on its Nitrogen8M_Mini SOM, but it starts at $299. Also note that CompuLab is pairing a Mini-based UCM-iMX8M-Mini module with an open-spec carrier, but the combo costs $236 in single units.
Aimed at IoT and robotics, the Odroid-C0 is a smaller (65 x 56mm), somewhat stripped-down version of the Odroid-C1+ (see below). It has the same quad-core, Cortex-A5 Amlogic SoC and offers the same Ubuntu and Android 4.4 support with GCC 4.9.2 Linux toolchain. Coastline ports are limited to a single HDMI, but an optional Connector Pack lets you solder on real-world connections for unpopulated interfaces. These include dual USB host, serial console, IR, I2S, and an RPi-like 40-pin interface. A battery connector with charging circuit supports an optional 3.7V Li-Po. Internet connectivity requires an optional WiFi dongle. As with all Odroid boards, the price includes worldwide shipping.
The Odroid-C1+ upgraded the earlier Odroid-C1 with features like a full-size HDMI port, a standard heatsink, and I2S audio and micro-USB-OTG links. The C1+ has a price, footprint, and feature set that is almost identical to the original, 32-bit Raspberry Pi 2, but has a faster processor, and supports Android 4.4 in addition to Ubuntu 14.04. The C1+ is further equipped with a microSD slot and optional eMMC, as well as GbE, serial console, ADC, and a Pi-compatible 40-pin connector.
The Odroid-C2 came in seventh and eighth place in our last two SBC reader surveys. It has the same 85 x 56mm size and layout as the Odroid-C1+ and Raspberry Pi 3, but advances to a quad -A53 Amlogic S905 SoC. It’s faster than the RPi 3 or 3+, but there’s no WiFi or Bluetooth, and the price is higher. The C2 doubles the RAM of the C1+ to 2GB and offers a choice of optional storage between up to 64GB of eMMC or an 8GB or 16GB SD 3.01 compatible UHS-1 microSD card. The SBC can output 4K @ 60Hz video, and has almost everything the C1+ has, including GbE and HDMI ports, four USB host ports, and a 40-pin RPi connector. Images are available for Android 5.1 or Ubuntu 16.04, based on a Linux 3.14 LTS kernel.
The worldâs first Intel Gemini Lake hacker board — and likely the fastest board in our roundup — touched down last November after an October announcement. The Odroid-H2, which sells without RAM or eMMC for $111 or with a minimal 4GB/8GB for $160, offers maximum memory support of 32GB RAM and 128GB eMMC. Sadly, itâs been out of stock the last few months due to production delays from Intel. In February, Hardkernel suggested production should resume this summer, so weâll give it the benefit of the doubt here. Hardkernelâs first x86 based Odroid runs Ubuntu 18.10 on a 2.3GHz Celeron J4105 from Intelâs Gemini Lake — the latest generation of its lower-power Atom SoC line. The 110 x 110mm SBC offers 2x SATA 3.0, 2x GbE, HDMI and DP, 4x USB (2x 3.0), and an M.2 slot for NVMe storage. Other features include a 14-20V DC input, RTC, and a heatsink that supports 70Â°C temperatures at full load.
The Odroid-N2 is arguably the most significant SBC launch of early 2019. It replaces the RK3399-based Odroid-N1, which never came to market. The N2 features a faster new hexa-core Cortex-A73 and -A53 based Amlogic S922X with advanced Mali-G52 graphics for around the same price as the most competitive RK3399 boards. Available with 2GB or 4GB RAM, the 90 x 90 x 17mm SBC runs Android 9 Pie and Ubuntu 18.04 LTS with Linux 4.9.162 LTS. The board has a GbE port and optional USB WiFi adapter that fits into one of the 4x USB 3.0 host ports. You also get micro-USB OTG, composite A/V, and an HDMI 2.0 port with [email protected] with HDR, CEC, and EDID support. Thereâs also an RPi-like 40-pin header and a 7.5-20V DC input plus RTC, IR, console, and options including SPDIF and a cooling fan.
Despite its age, the Odroid-XU4 moved from fourth to third place in our last SBC reader survey. It uses the same octa-core Exynos5422 and Mali-T628 GPU as the earlier XU3, and provides a GbE port, audio-enabled HDMI, 2x USB 3.0, and a single USB 2.0. Thereâs now an Odroid-XU4Q model, which is identical, except that the fan is replaced with a heatsink. Both models are discounted to $49, down from the usual $59. The XU4 has a 12-pin GPIO header and 30-pin expansion connector. Options include USB-based SATA 3.0, an I/O board, and various wireless add-ons. The Odroid-XU4 ships with several versions of Android up to 7.1 Nougat, as well as Ubuntu 16.04, based on a Linux 4.14 LTS kernel. A lightweight version of the board powers a $49 Odroid-HC1 mini-PC. Up to four XU4 SBCs can be loaded onto a $220 Odroid-MC1 cluster computer. Hardkernel also offers a stackable, single-unit Odroid-MC1 Solo version for $48, and the XU4 powers the $54 Odroid-HC2 NAS platform.
Last December, Onion released an Omega2 Pro model that runs OpenWrt on the same MIPS-based, WiFi-equipped MediaTek MT7688AN SoC as its Omega2 compute module, but with real-world USB and micro-USB ports. The SBC has shipped and is still available for $49 on Crowd Supply. An $82 package adds Ethernet and OLED expansion modules via the new 30-pin expansion connector. A $169 package gives you all eight modules, including GPS, servo, relay, NFC/RFID, ADC, and prototyping options. Unlike the MT7688AN-equipped LinkIt board, thereâs no Arduino companion chip. The 73 x 44mm SBC boosts boosts RAM to 512MB (128MB RAM with 384MB flash swap file) and flash to 8GB compared to the Omega2 module. The 2.4GHz WiFi radio comes with AP support and antenna. Onion recently launched a sandwich-style, $99 Omega2 LTE SBC expected to ship in August. It has the same processor as the Omega2 Pro but implemented on a removable Omega2S+ module with only 128MB RAM and 32MB flash. The board adds battery support and a Type-C port plus a Quectel EC25 chipset with Cat 4 LTE and GNSS.
Most of Shenzhen Xunlongâs Orange Pi boards have 40-pin Raspberry Pi compatible connectors and low prices that are matched with generous, under-$4 shipments to the U.S. Linux and Android OS images available on the Orange Pi site vary widely by board. The first Orange Pi on our list is somewhat atypical in that it offers an integrated 2G GSM/GPRS/EDGE baseband, 2G antenna, and SIM slot. Considering the decline of 2G services, the appeal may be limited. The 68 x 42mm Orange Pi 2G-IOT can withstand -10 to 65Â°C temperatures, and runs Android 6.1, Ubuntu Server, Debian, or Raspbian on a single-core, Cortex-A5 RDA RDA8810PL SoC (typically 1GHz). The 2G-IOT offers a WiFi/BT module, USB 2.0 host and micro-USB OTG ports, and LCD, MIPI-CSI, and audio links. Thereâs also an RPi-style 40-pin connector. The board has dropped to $9.90 at AliExpress.
The only new Orange Pi of early 2019 is one of the most hotly anticipated models in years. It taps the same Allwinner H6 SoC as the $20 Orange Pi One Plus and $25 Orange Pi Lite2, but adds a few more features, including a mini-PCIe expansion slot and 2GB RAM and 8GB eMMC options. The 90 Ã 64mm Orange Pi 3 is larger than the earlier H6-based Orange Pi models but is still limited to the same 26- rather than 40-pin GPIO header. Other features include microSD, GbE, 802.11ac, BT 5.0, HDMI 2.0a, audio AV, mic, IR, micro-USB 2.0, and micro-USB OTG. OS support includes Android 7.0, Ubuntu, Debian, and an experimental Linux 4.19 kernel available from Armbian.
The Orange Pi 3G-IOT provides a middle-ground option between the Orange Pi 2G-IOT (above) and Orange Pi 4G-IOT (below). There are two SKUs: a 3G-IOT-A model with 256MB RAM and 512MB eMMC and a 512MB/4GB 3G-IOT-B model. Thanks to its budget smartphone oriented, dual -A7 MediaTek MT6572 SoC, thereâs built-in support for 3G GSM, WiFi, BT, GPS, and FM. The 68 x 52mm board has little in common with the other IOT branded Oi rkrange Pi boards. The modest feature set includes an LCD interface, MIPI-CSI, audio jack and mic, and USB 2.0 host and micro-USB power ports. You also get a 40-pin expansion connector. An Ubuntu 16.04 image is now available in addition to Android 4.4.
Despite the similar names, the new Orange Pi 4G-IOT has little in common with the lower-end Orange Pi 2G-IOT and 3G-IOT SBCs except for its integrated cellular modem, which in this case is 4G LTE. Thereâs no Ethernet port, but you also get WiFi, BT, FM, and GPS. The 4G-IOT is typical of many Orange Pi boards in that it has a Raspberry Pi footprint (85 x 55mm) and 40-pin header. An HDMI port is available along with LCD, camera, and audio connectors. Other features include 3x USB OTG host ports, a micro-USB port, an IR receiver, and fingerprint reader support. Ubuntu 16.04 has recently joined the original Android 8.1 support.
The 60 x 30mm Orange Pi i96 was the second 96Boards IoT Edition (IE) board after Seeedâs BLE Carbon and is still the only one to run Linux. The SBC, which sells for $8.80 on AliExpress, uses the same 1GHz, Cortex-A5 based RDA8810PL SoC adopted by the $10, 68 x 42mm Orange Pi 2G-IOT, but without the 2G GPRS baseband. The SBC implements the âStandard Microâ IE formatâs 40-pin low-speed expansion connector option required by the âExtendedâ format, rather than the 30-pin subset used on the Carbon board. The Orange Pi i96 offers Android, Ubuntu, Raspbian, and Debian images. Features include WiFi/Bluetooth with external antenna, as well as microSD, USB host, and micro-USB OTG ports. There are no LCD or audio interfaces, but you get a CSI camera interface, 3x GPIO, and a 40-pin connector.
The fetchingly priced Orange Pi Lite, a WiFi variant of the Orange Pi One, offers the 1.2GHz version of the quad-core Allwinner H3 SoC, compared to 1.6GHz on the Orange Pi PC. It was followed by the similar Orange Pi Lite2, which swaps out the H3 for an H6 and doubles the RAM to 1GB. The Lite2 has the same 69 x 48mm footprint and much the same layout and feature set as the Lite. The big change was the shift to the quad- A53 H6 SoC, which is not only faster than the H3, but offers HDR and other media-related goodies. The Lite2 switches one of the two USB host ports to USB 3.0 and swaps out the WiFi-only chip for a faster 802.11ac with Bluetooth 4.1 and an antenna. Other enhancements include a PMU and an upgrade to Android 7.0. Ubuntu and Debian are also supported. The sacrifice here is that the 40-pin header has shrunk to 26 pins.
Selling for $20 on AliExpress, the Orange Pi One Plus essentially replaces the Allwinner H3-based Orange Pi One, which is still available for $10 at AliExpress. The One Plus has as an almost identical feature set, layout, and 68 x 48mm footprint as the One, and advances to Allwinnerâs quad-A53 H6 SoC with Mali-T720 GPU. The H6, which is also now available on the Orange Pi 3 (see below), features [email protected] (H.264) or [email protected] (H.265) decoding, both with 10-bit HDR. Other differences include a doubling of RAM to 1GB, a GbE port instead of 10/100, and HDMI 2.0a instead of 1.3. On the other hand, youâre limited to an old-school 26-pin connector instead of an RPi 3-compatible 40-pin link. Other features are identical, including USB host, micro-USB OTG, microSD, IR, mic, and MIPI-CSI I/O. Debian Jessie Ubuntu, and Android 9.0 are on tap.
The $15 Orange Pi PC provides an Allwinner H3, a Raspberry Pi-like 85 x 55mm footprint, and RPi-compatible 40-pin expansion. It has twice the RAM of the Lite and the original One models, and provides microSD, HDMI, CVBS, CSI, and 10/100 Ethernet connections. You also get 3x USB host ports and a micro-USB OTG. A newer Orange Pi PC Plus model adds 8GB of eMMC flash. A more advanced version of this design can be seen in the quad -A53 Orange Pi PC 2 below. The Orange Pi PC has a long list of OS choices, including Android 7.0, Ubuntu 16.04, Lubuntu, Debian, and Raspbian, OpenSUSE, Arch, and more, while the PC Plus offers a smaller selection.
The Orange Pi PC 2, which is available for $20 at AliExpress, builds on the Orange Pi PC design, but advances to a quad -A53 Allwinner H5. The PC 2 has the same footprint, 40-pin header, and features of the PC and PC Plus. It moves up to Gigabit Ethernet, but lacks the onboard eMMC of the Plus model, thereby depending solely on microSD.
In 2017, the Orange Pi Plus 2E replaced the Orange Pi Plus 2. The Plus 2E swaps out the four-port USB hub for three separate USB ports and removes the SATA interface. The 2E similarly runs distros including Lubuntu, Raspbian, and Android on a quad-core, Cortex-A7 Allwinner H3 clocked to 1.6GHz. The 108 x 67mm SBC provides GbE, WiFi, micro-USB, microSD, HDMI, CVBS, CSI, and an RPi-compatible 40-pin connector.
Like the $20 Orange Pi PC 2, the $36 Orange Pi Prime gives you a quad -A53 Allwinner H5, a 40-pin RPi header, and 3x USB host ports. It also similarly provides micro-USB OTG, HDMI, GbE, microSD, CVBS, audio, and MIPI-CSI connections. This larger, 98 x 60mm SBC doubles the RAM to 2GB and adds WiFi, Bluetooth, and -10 to 65Â°C support. Images are available for Android, Debian Desktop and Server, Ubuntu Desktop, and Arch Server.
The Orange Pi R1 stands out by combining a tiny 60 x 45mm footprint and low price with dual 10/100 Ethernet ports, one of which is USB-based. Aimed at tiny gateways like the similarly Allwinner H2 based Orange Pi Zero boards, the headless R1 is equipped with WiFi with antenna, plus a microSD slot and micro-USB 2.0 OTG port with power input. You get a 26-pin header compatible with old RPi boards, plus GPIO, serial debug, and a 13-pin interface that includes TV out. Android 5.1, Ubuntu Xenial, Debian, Armbian, and OpenWrt are on tap. The R1 sells for $14 on AliExpress.
The first RK3399-based Orange Pi was one of the most affordable RK3399 SBCs when it launched, but cheaper models have pushed it to the middle of the pack, even after dropping to $89 at AliExpress. The Orange Pi RK3399âs high-end feature set is very close to that of the Firefly-RK3399, with GbE, WiFi-ac, BT 4.1, and a wide array of display, camera, and audio features. The only major difference is that all four of its USB 2.0 connections are coastline ports. There are also USB 3.0 Type-C, and HDMI 2.0 orts, plus an HDMI input, DP 1.2, eDP, and 2x MIPI-DSI and -CSI interfaces. Audio features include SPDIF, I2S, and a 3.5mm jack. For expansion you get both a 40-pin connector and a mini-PCIe slot with mSATA support and a SIM slot. A second mSATA interface is standard. The 129 x 99mm SBC provides an array of sensors and runs Android 6.0 or Debian 9.
While most of the 64-bit Orange Pi models use the Allwinner H5, the 2GB Orange Pi Win Plus taps the older Allwinner A64, which is much the same except for its weaker Mali-400 GPU. The Win Plus follows a similar, but 1GB-limited Orange Pi Win, which was recently discontinued. The Win Plus can run Android, Debian Server and Desktop, Raspbian Desktop and Server, and Ubuntu Desktop/Server Xenial/LXDE/XFCE. The 93 x 60mm SBC is only slightly smaller than the similarly priced and configured, H5-based Orange Pi Prime. Like the Prime, the Win Plus provides micro-USB OTG, HDMI, GbE, microSD, audio, MIPI-CSI, and 40-pin RPi connections. It similarly supplies WiFi and Bluetooth and offers -10 to 65Â°C support. Differences include a MIPI-DSI LCD interface on the Win Plus in place of RCA/CVBS/AV, and the availability of 4x USB host ports instead of three. You also get optional eMMC.
The Orange Zero Plus 2 H3 and Orange Pi Zero Plus 2 H5 are rev’d up versions of the Orange Pi Zero. The Zero, in turn was recently upgraded to an Orange Pi Zero H2+, with the same features as the Zero, but with a slightly improved Allwinner H2+ instead of an H2. All three boards have the same tiny, 48 x 46mm footprint, but with different processors. The Orange Pi Zero Plus 2 H3 offers the Allwinner H3, which adds 4K support. The Orange Pi Zero Plus 2 H5 advances to a quad -A53 Allwinner H5, which also moves up to a Mali-450 GPU. Otherwise, the H3 and H5 devices are identical. Compared to the Zero H2+, the H3 and H5 models remove the mic, USB 2.0 host, and 10/100 Ethernet port. Yet, the headless Zero H2+ is limited to an AV-out interface available via a 13-pin function header, while the Zero Plus 2 H3 and H5 boards add an HDMI port and MIPI-CSI. They also add 8GB eMMC and Bluetooth 4.2, which is provided on an Ampak AP6212 module along with the previously supplied WiFi. It all looks good for low-cost multimedia, except that the H5 version could really use a 1GB RAM option.
After contributing its TI AM3358 based OSD335x SiP module to the BeagleBone Black Wireless and supplying its smaller OSD335x-SM module to the PocketBeagle, Octavo launched its own open-spec BeagleBone clone based on the OSD335x-SM. The 108 x 54mm OSD3358-SM-RED is billed as a development platform for prototyping Octavo OSD3358 SiP based devices. Unlike the BB Black Wireless, thereâs no WiFi/BT module, but thereâs a GbE port, and you get 16GB eMMC compared to 4GB on the other BeagleBones. Like the BeagleBone Green, you get 4x USB host/device ports plus a micro-USB port. Other features include a micro-HDMI port, a pair of BeagleBone expansion connectors, a 9-axis IMU, a LiPo connector, and temperature and barometer sensors.
The original Pepper that appeared back in 2013 was replaced with three new models, two of which are covered here. The Pepper boards have a TI AM3354 SoC that lacks the PRU MCUs of the original AM3359 but provide a 3D-ready PowerVR GPU. The $169 Pepper 43R and 43C are very similar, but the Pepper DVI-D is sufficiently divergent to deserve its own blurb below. The Pepper 43R can drive resistive touchscreens while the Pepper 43C supports capacitive. Both are available with optional 4.3-inch Newhaven touchscreens. The 43R version also adds a level shifter and a TI step-down converter. Both boards have a GbE port, microSD slot, dual micro-USB ports, a USB console port, and a TI WiLink 8 WiFi/BT 4.1 LE module. The Pepper 43 boards are further equipped with 20-pin GPIO, an audio jack, LiPo battery support, a PMIC, and LEDs. The boards can be further customized in the Gumstix Geppetto online design and manufacturing service.
The Pepper DVI-D has the same size, TI AM3354 SoC, and 512MB RAM as the Pepper 43R and 43C (see above), but with a much lower price and a different layout and purpose. Instead of supporting touchscreens, the Pepper DVI-D features an HDMI port (via DVI-D) to support HD output instead of 720p. Other features include a microSD slot, GbE port, audio jack, console port, USB host port, and dual micro-USB device ports. As with the Pepper 43 boards, images are available for Yocto, Ubuntu, and Android. A community portion of the site shared with other Gumstix developers provides projects and tutorials. Like the other Peppers, the SBC is designed with the Gumstix Geppetto DIY design service.
The PICO-PI-IMX7 and the other Android Things kits listed here are still available, but perhaps not for much longer considering Googleâs recent decision to focus the increasingly proprietary Android Things on OEM-built smart speakers and displays. The PICO-PI-IMX7 has the same RPi-like, 85 x 56mm footprint and almost all the same features of the PICO-IMX6UL-KIT (PICO-PI-IMX6UL), which has been discontinued, but is still available for $84 until it runs out at Digi-Key. The PICO-PI-IMX7 advances to a faster and still very power efficient, dual-core i.MX7 SoC and swaps out the MikroBus connector in favor of a MIPI-CSI interface. Thereâs also a $179 PICO-PI-IMX7-STARTKIT model that adds a camera module and a 5-inch, 800 x 480 capacitive touchscreen. A $199 PICO-PI-IMX7-STARTKIT-RAINBOW-HAT (AKA Android Things Starter Kit) is like the regular STARTKIT but adds Pimoroniâs Rainbow HAT for sensors, displays, and servo I/O.
The PICO-PI-IMX8M is a COM-and-carrier variant of the Wand-Pi-8M SBC, which has long been out of stock without a hint of a return. Now itâs the PICO-PI-IMX8M thatâs in short supply. There are a few 2GB and 4GB boards left, but the 1GB model will take four weeks for shipment. The good news is that 16GB instead of 8GB eMMC is now standard for the original price. The PICO-PI-IMX8M incorporates a PICO-IMX8MQ13-R20-E08-9377 module equipped with the same quad -A53, 1.3GHz NXP i.MX8M Quad SoC as the Wand-Pi-8M. (Thereâs no backward compatibility to earlier PICO COMs.) The PICO-PI-IMX8M similarly offers a RPi-like footprint, layout, and 40-pin header as well as GbE, 4K-ready HDMI 2.0, and micro-USB debug ports. However, the USB 3.0 Type-C and 3.0 host ports have been swapped for USB 2.0 versions. Other features include 4-lane MIPI-CSI and DSI, I2S audio, and a reset button. WiFi-ac and Bluetooth 4.2 are available on all but the Lite model. The boards support 0 to 50Â°C temperatures and offer shock and vibration resistance. OS support includes Linux, Yocto, Ubuntu, and Android. Technexion also offers a sandwich-style, i.MX8M Mini based PICO-PI-IMX8M-Mini dev kit that does not appear to be an open-spec board and which exceeds our pricing limit at $250 to $265. Itâs also working on a series of i.MX-based AXON SBCs.
This Raspberry Pi imitator provides microSD, HDMI, Fast Ethernet, audio, dual USB 2.0 host, and micro-USB ports. The 127 x 79mm board offers a Pi-compatible, 40-pin connector, a 14-pin Euler connector, an RTC, and -20 to 70Â°C support. Compared to the original A64 model with 512MB RAM, both the 1GB and 2GB A64+ models and newer 2GB LTS model boost Ethernet to GbE and add MIPI-DSI and -CSI with touchscreen and camera options. The LTS model originally used a very similar Allwinner R18 SoC but has not changed to the A64. The LTS board adds a 5-year longevity guarantee, microSD bootability, SPI boot flash, and optional, up to 128GB eMMC. Of the standard A64+ models, only the 1GB version is in stock, and Pine64 recommends that buyers opt for the LTS version. Mainline Linux based distros include Android 6.0/7.1, Xenial Mate 1.8.1, Arch 1.2.1, Armbian 1.1.1, openSUSE 1.9.1, OpenMediaVault 1.7.1, LibreELEC 1.3.1, NEMS Linux 1.5.1, AOSP 1.4.2, and the Volumio audio player. Pine64 also sells a SODIMM-style SoPine A64 COM featuring the guts of the Pine A64 that is also available with a baseboard for $35. Thereâs also an open source Pinebook laptop based on the same A64 processor, sold for $89 (11.6-inch) or $99 (14-inch).
The Pine H64, went on sale in Feb. 2018 as a limited-edition developer model that quickly went out of stock. In early March of this year, it was replaced by a Model B version that similarly features the high-end Allwinner H6 SoC. The video-focused H6, which is also found on the Orange Pi One Plus and Orange Pi Lite 2, features a Mali-T720 GPU and can push out [email protected] with HDR video over the Pine H64âs HDMI 2.0 port. The Model B adds a 2.4GHz WiFi and Bluetooth 4.0 module with antenna, as well as an SPDIF audio interface. It also trims down to an 86 x 54mm footprint and adjusts the layout so that it can use the cases for Pine64âs Rock64 SBC. The previous, dysfunctional mini-PCIe slot and 1GB RAM option have been removed. The Pine H64 is equipped with GbE, 2x USB 2.0, and optional eMMC. Like the Pine A64, it offers 40-pin and 14-pin Euler expansion connectors, and it adds a mini-PCIe slot. Thereâs an Android 7.0 image and Armbian Debian Stretch is under development.
BeagleBoard.orgâs tiny PocketBeagle, which has dropped to $21 at Arrow, barely qualifies as an SBC thanks to its microSD slot and micro-USB port. Like the BeagleBone Blue and BeagleBone Black Wireless, itâs built around an Octavo OSD335x SiP, which includes the BB Blackâs AM3358 SoC with PRUs and PowerVR GPU along with 512MB RAM. The 56 x 35mm PocketBeagle is about the same size as the Raspberry Pi Zero. Thereâs no eMMC, wireless, or Ethernet port, but you can plug this COM-like board into a laptop as a USB key-fob. This lets you program the device using a web browser that provides access to the Linux command line and text editor. The PocketBeagle is not a true BeagleBone clone since it lacks dual 46-pin connectors for Cape add-ons, and it has 72 pin headers instead of 92. Yet, the Debian-driven SBC should run any BB Black software that does not access the unavailable pins.
Even when factoring in $5 to $25 more to add various cables and adapters, the $5 Raspberry Pi Zero is still a good deal for space-constrained IoT hacking projects. The 65 x 30mm Zero upgrades the same old-school ARM11 processor found on the Raspberry Pi A+ and B+ to 1GHz speed. The COM-like SBC ships with a microSD slot, a pair of micro-USB ports, and a mini-HDMI port with audio support, as well as an unpopulated composite video header for the VideoCore IV GPU. Missing are all the USB ports, DSI and CSI ports, and audio jacks found on the RPi 3.
The Raspberry Pi Zero W is identical to the RPi Zero except for the addition of the same Cypress CYW43438 wireless chip found on the Raspberry Pi 3, providing 802.11 b/g/n and Bluetooth 4.1 with BLE. The Zero W is available starting at only $10 but you need the same add-ons as the Zero to get real-world video and USB ports. The newer Raspberry Pi Zero WH model adds a soldered 40-pin GPIO header to the Zero W for easier prototyping and access to the GPIO Expander tool.
Last November, the long-awaited update to the retired, $20 Raspberry Pi Model A+ arrived with the same 65 x 56mm footprint, but also a raft of new features indicated by the â3â in the middle of the name. The Raspberry Pi 3 Model A+ has the same 1.4GHz quad-A53 SoC, dual-band WiFi-ac, and 40-pin, HAT-compatible GPIO of the larger, higher-end RPi 3B+. Other similar features include the HDMI port, microSD slot, DSI and CSI interfaces, and composite port. The biggest sacrifice is the halving of RAM to 512MB. Although this is twice the allotment of the earlier A and A+ models, a 64-bit SoC like this deserves better. Thereâs also no LAN port, and instead of 4x USB 2.0 host ports, you get one.
The Model 3 dominated the hacker board market for years until it was eclipsed by the RPi 3B+. Recently, Ameridroid launched promotional $34 price for the typically $35 board that includes a free 16GB microSD card pre-loaded with NOOBS. Most RPi imitators are more open source than the RPi 3, which like its siblings does not provide complete schematics. Yet, the Pi boards offer guaranteed Raspberry Pi add-on compatibility, the widest range of software support, and membership in a thriving community. The largely open source VideoCore CPU adds to the RPi 3âs reputation as a good choice for video applications. You can also buy a Raspberry Pi Model B 2 v1.2 for $35, but with a slower, 900MHz quad -A53 Broadcom SoC and no WiFi or Bluetooth.
The Raspberry Pi 3 Model B+, which was the runaway leader of our June 2018 SBC reader survey, has the same price and much the same layout and feature set of the RPi 3 Model B, but with both major and minor improvements. The 3B+ provides a faster, 1.4GHz Broadcom SoC and pre-certified, dual-band 802.11ac and Bluetooth 4.2. The LAN port has moved from a 10/100 port to a USB-powered, up to 300Mbps Gigabit Ethernet port, and thereâs even a $20 Power-over-Ethernet POE HAT option. The initial PoE HAT had regulator problems, but RPi Trading offered a refund and a repaired model is now available. Other RPi 3B+ improvements include a better PMIC, a heat spreader, and 0 to 50Â°C support.
The Renegade Elite launched on Indiegogo last July, and although it did not meet its flexible funding goal, Libre Computer finally released the board and sells it for $100 on LoverPi as the Libre Computer Board ROC-RK3399-PC. Co-developed with Firefly and touted for its excellent mainline Linux support, the 120 x 72 x 11.9mm Renegade Elite is a bit more affordable than most RK3399 boards. This update to the Rockchip RK3328 powered Firefly-ROC-RK3328-CC (Renegade) offers all the high-end features youâd expect from an RK3399 board and more. You get 4GB RAM, HDMI 2.0, and 2x USB Type-C ports with DP support. Standout features include a GbE port with optional Power-over-Ethernet, as well as dual 60-pin expansion headers, with the high-speed connector supporting PCIe x4 2.1.
A year ago, Seeed upgraded its original ReSpeaker far-field voice control board with a v.2.0 model that moved from running OpenWrt on a single-core MIPS CPU to running Debian on a quad -A7 RK3229 SoC. The RK3229 is implemented along with 1GB DDR3 via an âAxol Coreâ module. The hexagonal ReSpeaker v2.0 features a 6x mic array with 8-channel ADC and a 16-meter wake-word range. Unlike the original, audio is processed directly on the RK3229 with a mix of open source and proprietary algorithms, and you get 3.5mm and JST 2.0 audio outputs. Other features include 4GB eMMC, a microSD slot, a fast Ethernet port, and WiFi/BT. You also get HDMI 2.0, 2x USB 2.0, and micro-USB OTG and device ports plus GPIO and Grove expansion. The ReSpeaker has some new competition in an open-spec, Allwinner backed Hichips-Parrot mic array board SBC, which only costs $80, but is disqualified here for its 10+ minimum purchase requirement.
MYIR’s open-spec, 100 x 65mm Rico Board taps TI’s single-core, Cortex-A9, Sitara AM437x SoC. The SBC integrates HDMI, GbE, and dual USB ports, as well as a 24-bit LCD interface that supports optional 7-inch touchscreens. You also get camera interfaces and dual 40-pin expansion connectors with support for CAN and industrial I/O. Thereâs no organized open source community, but you get schematics and detailed documentation.
Like the Firefly-ROC-RK3328-CC SBC (AKA Libre Computerâs Renegade), Pine64âs Rock64 combines Rockchipâs mid-range, quad -A53 RK3328 with a Raspberry Pi like 85 x 56mm footprint and expansion. The Rock64 lacks the RPi 3âs WiFi/BT module, except for optional, $7 to $22 USB dongle, and you wonât find any DSI and CSI interfaces. In addition, it only has 3x USB ports instead of four. However, one of those three is a faster USB 3.0 port and another is an OTG port. The microSD slot and empty eMMC socket are bootable, and you get a GbE port and HDMI 2.0 port with 4K HDR support. Options include $8 or $13 enclosures, a variety of $9 power supplies, and a $15 audio DAC board. OS support includes Android 7.1 and Linux distros including Debian, Armbian, Bionic, and more.
Selling for $39 at Allnet China (or $74 at Innet24 in Germany), the Rock Pi beats the $50 NanoPi Neo4 as the most affordable 1GB-RAM RK3399 SBC around, and its $57 2GB model edges out the 2GB, $60 RockPro64. Thereâs an A model without WiFi/BT and a B model with. Each model offers 1GB, 2GB, 4GB RAM configurations, and each is optionally available in a âPerformance Setâ kit version with a power adapter, case, heatsink, and USB cable. Like the RK3399-based NanoPi M4, the Rock Pi 4 closely matches the Raspberry Pi layout and feature set, including the 40-pin connector. Thereâs a native GbE port that is claimed to work with the Raspberry Pi PoE HAT. Unlike the NanoPi M4, it adds an M.2 slot for NVMe SSDs, but it lacks the M4âs additional 24-pin GPIO interface. You get a pair each of USB 3.0 and 2.0 ports and a 4K-ready HDMI 2.0 port in addition to 2-lane MIPI-DSI and -CSI. Other features include an audio jack with mic, an RTC, and a USB Type-C port for power. The SBC has a 0 to 80Â°C range, a 5.5-20V input, and support for Android 9.0. Debian, and Ubuntu Server.
The RockPro64 is one of the most affordable RK3399 boards around and stands out with its full-size PCIe x4 expansion slot. The RockPro64 has the same 127 x 79mm dimensions and many of the same features found on the Allwinner H6 based Pine H64. You get HDMI, MIPI-DSI, eDP, 2x MIPI-CSI, Parallel camera, USB 3.0, 2x USB 2.0, and DisplayPort 1.2 via USB Type-C. For communications, thereâs a GbE port and optional, $16 WiFi-ac with Bluetooth 4.1. MicroSD. audio links are available along with a 40-pin RPi-style connector. Thereâs support for Android 8.1, Ubuntu, Arch, and Debian.
Last September, the delayed Rock960 appeared as the heir apparent to Vamrsâ larger, pricier Rockchip RK3399 Sapphire SBC, which is unavailable. The 85 x 55mm Rock960 provides the usual 96Boards low- and high-speed connectors, as well as HDMI 2.0 and DP support via USB Type-C OTG. The SBC provides USB 3.0 and 2.0 ports, MIPI-DSI and -CSI, and an NVMe-ready M.2 M-key slot via an optional $10 adapter. The 8-18V board supports Android 7.1 AOSP, Debian, Ubuntu, Fedora, LibreELEC, Lakka, and FlintOS, among others. In January, Vamrs announced a feature-reduced âModel Câ version of the Rock960 (see below), and it collaborated with Rockchip on a larger Toybrick RK3399Pro with the same AI-enhanced RK3399Pro SoC due to arrive soon on the Khadas Edge-1S. The Toybrick exceeds our $200 limit, selling for $249 with 3GB/16GB and a rich set of features, including 4x PCIe lanes and a mini-PCIe slot. This appears to have replaced the previously tipped 96Boards EE compatible Rock960 Enterprise Edition âFicusâ board, which has yet to reach market. In April, Linaro and Beiquicloud announced an RK3399Pro-based TB-96AI module along with a carrier board, but the combo costs well over our $200 limit on Taobao. The module debuts a new 96Boards Compute Module spec along with an RK1808-based TB-96AIoT module that uses the same carrier, which is also over our limit.
In January, Vamrs announced a lower-cost version of its Rock960 called the Model C. The 96 Boards CE compatible board adds a 1GB configuration and boosts RAM to LPDDR4 but has an empty eMMC socket instead of 16GB or 32GB eMMC on the Models A and B, respectively. The USB 3.0 Type-C port with DP support has switched to a USB 2.0 Type-C without DP, leaving you only the HDMI 2.0 port. Finally, it uses a slower, lower-cost version of the dual-band 802.11ac module without 2Ã2 MIMO. Otherwise, itâs all the same, including the optional M.2 adapter with NVMe support. Vamrs sells the board from the link above, although itâs currently out of stock at Seeed.
The SAMA5D4 Xplained Ultra is a collaboration between Microchipâs Linux4SAM developer site and Newark Element14. The Linux-ready, IoT-focused SBC showcases Microchipâs SAMA5D4 SoC, which like the earlier SAMA5D3 is limited to a single Cortex-A5 core. The SAMA5D4 adds NEON, L2 cache, and security features, and several models support 720p video. The 138 x 88mm Xplained board ships with 512MB each of RAM and NAND flash, and offers partial Arduino compatibility. You also get HDMI, Fast Ethernet, and three USB ports.
Seeed’s Seeeduino Cloud, which has dropped in price by $20 since January, is a clone of the rebooted Arduino Yun (see farther above). Itâs also one of the few Linux-ready SBCs with full Arduino compatibility remaining on the market. The Cloud is a variation on its earlier Seeeduino Arduino clone, and similarly adds Arduino support and the ability to connect the company’s Grove sensor and I/O add-ons. By integrating Dragino’s HE computer-on-module, the Seeeduino Cloud provides a Yun-like Atheros AR9331 WiFi subsystem that runs OpenWrt Linux. Other features include 10/100 Ethernet, USB host, micro-USB, 20x DIO pins, 7x PWM channels, and 12x analog inputs. Like the Seeeduino, the Seeeduino Cloud eases the interface between Arduino firmware and complex web services, in this case via a YunBridge library.
Asus’ popular Tinker Board is still the only open spec hacker SBC from a major PC manufacturer. The original was replaced with a pricier Tinker Board S that added 16GB eMMC, HDMI-CEC support, a smart audio jack, and improved power management. Like the original, the S model offers a Raspberry Pi style size, layout, feature set, and 40-pin connector. Compared to the RPi 3 B+, the SBC has a faster, although 32-bit, processor with a more powerful Mali T760 GPU with upscaled 4K/30fps playback and twice the RAM. The SBC is equipped with WiFi, BT 4.0, a GbE port, and 4x USB 2.0 ports. You also get microSD, micro-USB, HDMI, MIPI-CSI, and MIPI-DSI. A community site is available with a forum, schematics, and other resources. In addition to Asusâ homegrown, Debian- and LXDE-based TinkerOS, thereâs an Android image available. The SBC is available at B&H Photo and Amazon. Asus recently unveiled upcoming Tinker Edge S and more industrial CR1S-CM-A boards based on the i.MX8M and Edge TPU equipped Google Coral SOM, as well as an RK3399Pro based Tinker Edge R.
Libre Computer, which makes Le Potato, Renegade Elite, and other SBCs fulfilled its Kickstarter orders for its Tritium (Libre Computer Board ALL-H3-CC) and is now selling it on Amazon, or for $5 more, on LoverPi. The Tritium runs Ubuntu 16.04 or Android 7.1 on a choice of Allwinner H2+ (quad -A7 with HD resolution), H3 (quad -A7 with 4K), or H5 (quad -A53 with 4K). Like Le Potato, the Tritium has a Raspberry Pi 3-like form factor, layout, and 40-pin expansion interface. The only difference we can see is the addition of an IR receiver. OS support includes Android 7, Ubuntu 18.04 LTS, Debian 9 Stretch, Armbian, and Raspbian. Options include 16GB eMMC ($20) and a $7 heatsink.
Like the larger Udoo Quad/Dual SBCs, the IoT-focused, 85 x 59mm Udoo Neo runs Linux or Android on a Cortex-A9 based i.MX6. The Neo, however, is optimized for the single-core i.MX6 SoloX variant and taps its Cortex-M4 MCU to mimic an Arduino. The specs differ slightly from the Kickstarter package referenced in the LinuxGizmos link above. The Udoo Neo Basic provides Ethernet, microSD, USB host, micro-USB OTG, micro-HDMI, LVDS with touch, and a Parallel camera interface. There’s also an Arduino connector, as well as GPIO, UART, CAN, PWM, I2C, and SPI interfaces. For $10 more, the Neo Extended bumps the RAM to 1GB, adds 3-axis motion sensors, and replaces Ethernet with a WiFi/Bluetooth module. The Neo Full, which continues to be out of stock but has a notification sign-up button, is identical to the Extended but offers both Ethernet and wireless.
Seco’s Udoo project offers three SKUs for its flagship, 110 x 85mm Udoo SBC. The Udoo Dual Basic and Udoo Dual provide the dual-core i.MX6 DualLite while the Quad has the quad-core i.MX6 with a higher-end Vivante GPU. All three boards integrate a Cortex-M3 based Arduino Due subsystem. The boards offer microSD, HDMI, LVDS with touch, audio, and CSI connections. You also get dual USB host and dual micro-USB ports, one of which is OTG. There are 76 GPIO pins in addition to the Arduino interface. The Udoo Dual adds WiFi and GbE connections, and the Quad also adds SATA.
The Udoo X86 is one of the more fully open source entries among the small crop of under-$200 x86 hacker boards. Only the $174, Celeron N316 based Advanced Plus version is eligible under our $200 limit, and itâs currently out of stock, but the notification button suggests it should return soon. Although the Udoo X86âs Intel Braswell SoCs are several generations old, having been followed by Apollo Lake and Gemini Lake, they similarly use a 14nm process and have a low, 5-6W TDP. An extensive feature list includes M.2, GbE, SATA III, HDMI, 2x DP, wireless, and 20x GPIO. Other features include 3x USB 3.0 ports, analog and digital audio I/O, plus an RTC, IR, and an IMU. There are also loads of options, including a heatsink, case, cables, and an M.2-based dual Ethernet module. The 120 x 85mm board runs Linux, Android, and Windows 7/8.1/10. A year ago, Secoâs Udoo Project launched the Udoo Bolt hacker board on Kickstarter, featuring AMDâs x86-based Ryzen Embedded V1000 SoC. Itâs currently on pre-order at Mouser, but starts at $332, well over our $200 limit.
Like the later UP boards, the original UP is not backed up with full schematics. Yet, the UP Community now supplies far more extensive documentation, including some schematics, as well as open source downloads, tutorials and support. The UP board runs Ubuntu 16.04, Ubilinux 4.0 Beta 2, OpenBSD 2.0, or Windows 10/8.1 on a quad-core, 1.44GHz/1.92GHz Atom x5-Z8350 of the 14nm Cherry Trail generation. The 85.6 x 56.5mm board not only looks like a Raspberry Pi, but it provides a 40-pin expansion bus via an Altera MAX V CPLD that is said to provide RPi 2 compatibility. The UP is equipped with a GbE port, a USB 3.0 OTG port, 4x USB 2.0 ports, and two USB 2.0 headers. Other features include HDMI, DSI, CSI, I2S, and eDP. Accessories on all the UP boards include fans, enclosures, wireless kits, cameras, touchscreens, cables, UPS batteries, and more. Other Cherry Trail SBCs include the smaller Up Core and the much more affordable Atomic Pi.
The UP Core, which began shipping to the public in Mar. 2018 after its 2017 Kickstarter launch, is a smaller, 66 x 56.5mm version of the UP board. It runs the same Linux and Windows software and offers a similar feature set except that you get WiFi and Bluetooth 4.0 BLE instead of a GbE port. The UP Core is limited to 2x USB 2.0 headers, compared to 4x coastline USB 2.0 ports and 2x USB headers on the UP board. Like the UP board, it also has single USB 3.0 and HDMI ports. Other features include dual MIPI-CSI, eDP, I2S audio, and a 100-pin docking connector with RPi HAT compatibility. The board has the same five configurations of RAM and eMMC as the UP board, with the same prices.
A year ago, Aaeon launched an UP Core Plus SBC on Kickstarter as the centerpiece of an UP AI Edge family that includes optional, AI add-on boards. The family also includes a higher end UP Squared AI Vision Kit based on the UP Squared board, which like most of the UP Core Plus configurations is beyond our $200 limit. The 90 x 56.5mm UP Core Plus is larger than the Intel Cherry Trail based UP Core and has a choice of three quad-core âApollo Lakeâ Atom SoCs. OS support is the same as the UP Core except that it also supports XenServer 7.2. The UP Core Plus is equipped with a DisplayPort, eDP, and 2x MIPI-CSI interfaces plus USB 3.0 host and OTG ports and 2x USB 2.0 ports. Dual 100-pin high speed GPIO connectors are compatible with UP board add-ons. Thereâs no Ethernet, but you get 802.11ac and Bluetooth, and there is a GbE port on the optional $49 high-speed I/O carrier board option. Thereâs also a $49 low-speed I/O carrier board add-on among the many other options including cooling systems, enclosures, mini-PCIe based 3G and LTE cards, and the UP AI Core module.
The Up Squared shipped to Kickstarter backers in mid-2017 and is now a bit pricier — only a few models fit under our $200 limit, including one of the two new Atom x5-E3940 models. The lower-cost Celeron models have delayed shipments due to shortages. The 90 x 86mm UP Squared offers 4K encode and decode, dual GbE ports, dual HDMI outputs, and SATA, M.2, and mini-PCIe expansion. You also get eDP, dual MIPI-CSI, 3x USB host, a micro-USB 3.0 OTG port, and both a 60- and 40-pin GPIO tied to an Altera Max 10 FPGA. OS support is the same as on the UP Core Plus, and the extensive hardware options also appear to be similar. In March, Aaeon posted specs for an UP Xtreme board with an Intel 8th Gen Whiskey Lake-U CPU. Due to launch on Kickstarter later this month, the feature-rich Xtreme is likely to exceed our $200 limit.
The sandwich-style Wandboard was of the earliest community-backed Linux SBCs along with the BeagleBone and Raspberry Pi. The original Wandboard received a âReloadâ update in early 2017 that added the i.MX6 QuadPlus as an alternative to the Quad model, bringing an improved Vivante GC2000+ GPU, an SPDIF audio interface, faster WiFi/BT, a new PMIC, and bug fixes. Features include dual microSD slots plus GbE, HDMI, camera, serial, USB, and USB OTG connections. The Dual lacks the Quad’s SATA connection, and the Solo also foregoes the WiFi and Bluetooth found on the Quad and Dual.
The Z-turn Board, which spun off a Z-turn Lite model (see below), runs Linux on a choice of two Xilinx Zynq SoCs which combine dual Cortex-A9 cores with two FPGA choices: the Zynq-7010 (28K logic cells) or Zynq-7020 (85K). The 102 x 63mm SBC features HDMI, GbE, and dual mini-USB ports, as well as a CAN port and a variety of sensors, buzzers, switches, buttons, and LEDs. Dual 80-pin expansion connectors express the FPGA signals and can be configured as LVDS pairs. A $139 kit version adds a power adapter, cables, and a 4GB data card. For software, you get a customized Linux 3.15 BSP.
Access Control Circuit Board
This cheaper, smaller (91 x 63mm), stripped-down version of MYIRâs Z-turn board offers a different mix of ARM/FPGA Xilinx Zynq options. The previous low-end model — the Zynq-7010 (28K logic cells) — is the Lite modelâs high end, and the new low end is the Zynq-7007S with 23K FPGA logic cells and only one Cortex-A9 core instead of two. RAM has been halved, but unlike the original Z-turn, you get 4GB eMMC in addition to the 4GB microSD card that ships with both boards. The Lite reduces the number of programmable I/O lines to 84 and omits features such as the HDMI and CAN ports, as well as temperature and motion sensors. MYIR also offers a $29, 91 x 63mm Z-turn Lite IO Cape designed specifically for the Lite that gives you a real-world HDMI port, as well as camera, LCD, Pmod, and GPIO interfaces. Note that Avnet recently launched an updated Ultra96-V2 96Boards CE with the 64-bit Zynq UltraScale+ MPSoC, but it starts at $249.
The A20-OlinuXino-Lime2 entry should have SATA on the feature list (as it is on its homepage). I’ve been happily using its predecessor, A20-Lime, as a local Armbian server (with OS pushed over to HD where it’s less vulnerable to corruption) for a few years, now, I expect the Lime2 is more-of-same.
