[Updated: Jan. 2, 2016] — Community backed, open-spec SBCs vary wildly, from sub-$10 minimalists to octa-core powerhouses. Here we present 64 Linux- and Android-friendly models.



In 2015, the number of open-spec, hacker friendly single board computers running Linux or Android has continued to grow while prices have dropped to unprecedented levels. Low-cost boards such as the Chip, Raspberry Pi Zero, and Orange Pi PC have set a higher bar for price/performance ratio, while on the high end, we saw the first 64-bit, ARMv8 hacker SBCs arrive at surprisingly low prices. Meanwhile, the board that matters most to makers around the world — the Raspberry Pi — was updated to a Pi 2 model with a modern quad-core, ARMv7 processor that opens up new applications and a wider range of Linux distributions.





In our first joint reader survey of community-backed boards with Linux.com in May 2014, readers rated their favorite SBCs from a list of 32. This jumped to 40 boards for our end-of-year 2014 SBC roundup, then 53 boards for our second survey, held in May 2015, with winners announced in early June.

For our 2015 end-of-year roundup — no surveys or prizes this time — we’ve identified 64 boards that fit our fairly loose requirements. Here, we accept any board with full specs and pricing that is either shipping now or expected to ship in the first six months of 2016. The requirements are otherwise the same as the most recent survey, including a $200 cutoff. Some of these boards offer optional configurations that go beyond that, but are also available in workable sub-$200 models.

Our list could actually be much longer than 64. Many vendors now have so many board options, it’s difficult to delineate between individual products and optional variations. Boards come and go, are modified, or are renamed and repriced. In some cases, we combine several products or link to other options in our descriptions below. We’ve limited our selection to five per vendor/project, which was difficult with a few vendors such as LinkSprite (pcDuino). Some still-shipping SBCs have dropped off the list due to the arrival of newer models that would appear to clearly eclipse older ones.

As with the May survey, we struggled over how to define an open spec hacker board. In general, we have accepted sub-$200 boards that are offered with extensive specs and schematics, and that support open source Linux or Android distributions. They also must offer at least a glimmer of community and technical support for individual developers, even if there’s no explicit open source licensing for creating derivative hardware.

Defining what constitutes an SBC was also a challenge, especially since many open-spec single board computers are actually sandwich-style assemblies consisting of a replaceable computer-on-module plugged into a baseboard. The increasing modularity of SBCs, including a growing number of expansion options sold in various kits, will make comparisons more difficult as time goes on. In general, however, we have accepted COM+baseboard combos and other kit devices.

The listed prices are the lowest we saw at publication, but the pricing on many of these boards is fairly fluid. Typically, the prices do not include free shipping, or if so, only to certain regions. Sometimes the shipping prices can be considerable, turning a $35 board, for example, into a $50 board.

Be on the lookout for this year’s hacker SBC survey, which will launch in May with lots of new boards — plus hacker SBC prizes for lucky readers.

Here, then, is our January 2016 list of 64 sub-$200 hacker friendly single board computers, in alphabetical order. Note: Convenient comparison tables showing all these boards compared by processor (type, cores, speed), RAM, and pricing may be found here. Enjoy!

Product page

Processor — Marvell IAP140 (4x Cortex-A53 cores @ 1.2GHz); Vivante GC7000UL GPU

Memory — 1GB LPDDR3 RAM; 8GB eMMC

Price — $75

Marvell’s first hacker board is a 96Boards form-factor SBC that runs Google’s lightweight, Android-based Brillo OS on Marvell’s new IAP140 SoC, also called the PXA1908. There’s considerable documentation (except for on the IAP140), and this appears to be an open spec board. The Andromeda Box Edge is listed for $75 by Arrow as the “RD-ANDROMEDA-140-01,” but was not shipping yet, and the Andromeda Box community site was in stealth mode. The SBC uses the same 85 x 54mm 96Board CE design, and provides the form factor’s signature 40- and 60-pin connectors. The SBC supports Google’s Weave networking protocol, as well as the 802.15.4 standard behind ZigBee and Weave’s associated Thread protocol. Other features include WiFi, Bluetooth, four USB ports, an HDMI port, and a microSD slot. An Andromeda Box Connect version for IoT gateways will follow in 2016. It runs on the same Marvell Armada 385 dual-core Cortex A9 SoC that debuted on SolidRun’s ClearFog Pro (see farther below). SolidRun also has a shopping page for the Andromeda Box Edge, suggesting that both boards may be built by SolidRun.

LinuxGizmos coverage

Product page

Processor — Qualcomm Atheros AR9331 (1x MIPS24k @ up to 400MHz)

Memory — 64MB DDR2 RAM

Price — $60

This update to the original Yún is currently offered only by Arduino Srl (Arduino.org), which broke off from Arduino LLC in early 2015. (We have given up on Arduino LLC’s much delayed Arduino TRE.) Like the original Yún, the Yún Mini runs the OpenWrt based Linino on Qualcomm’s 400MHz AR9331 SoC, and runs Arduino code on an Atmel Atmega32U4 chip. The Yún Mini is smaller (71.1 x 22.9mm), lighter (16 grams) and cheaper than the original, but it’s still pricier than most OpenWrt-on-Atheros boards. The Mini strips out the earlier Ethernet port, USB port, and microSD slot, and instead makes these and other interfaces available via optional “dog” accessories.

Arndale Octa

Company/project — ArndaleBoard.org, InSignal, Pyrustek

Price — $58

Just as the original dual-core Banana Pi was a near clone of the Raspberry Pi Model B, SinoVoip’s Banana Pi M2 closely resembles the Model B+, complete with a similar 40-pin expansion connector. Its A31 processor is competitive with that of the RPi 2 Model B. The M2 features GbE, WiFi, five USB ports, and a range of display and camera interfaces. There’s also a new octa-core M3 model (see below). In 2014, the Banana Pi project split between SinoVoip and LeMaker (BananaPi.org) factions, with the latter offering the dual-core Banana Pro (see below).

Banana Pi M3

Compared to the rival Banana Pi M2 from former partner SinoVoip, LeMaker’s own Banana Pi update sticks closer to the original, retaining the dual-core A20 SoC. It expands to a Raspberry Pi Model B+-like 40-pin connector, switches the SD slot to microSD, and adds WiFi and a micro-USB OTG port. Unlike the M2, it provides a SATA connector, but it only has two USB host ports compared to the M2’s four. LeMaker has also launched a self-branded board the LeMaker Guitar (see farther below), as well as a cheaper version of the 64-bit, 96Boards.org HiKey board.

Memory — 256MB, expandable to 1GB (single-core) or 2GB (dual) DDR3L RAM; optional eMMC or microSD card

Price — $170 to $240

The networking and IoT gateway focused ClearFog Pro SBC diverges from SolidRun’s i.MX6 based HummingBoard models by tapping a new Cortex-A9 SoC from Marvell. Like the HummingBoards, it’s an open spec, sandwich-style board with separate wireless, storage, and enclosure options. The Pro is notable for its six switched Gigabit Ethernet ports plus a standard GbE port. A ClearFog Base model that has yet to be priced will be limited to dual standard GbE ports, among other minor differences. Both models let you choose between 38x-MicroSOM A380 or A388 modules with one or two Armada 38x processor cores, respectively. Additional features include M.2, mSATA, USB, dual mini-PCIe, and a GPIO-based MikroBus header for MikroElektronika Click modules. No display ports are provided on this 225 x 100mm (Pro) board, which offers a wide-range power supply.

Memory — 256MB DDR3 RAM; 512MB flash

Price — $53 to $120 with Click module add-ons

Imagination’s IoT-focused follow-on to the Creator CI20 won’t ship to Kickstarter backers until April, and probably won’t go on sale again until then. While early bird packages started at 35 Pounds ($53), the retail price may be more like 80 Pounds ($120). The CI40 tosses out the CI20’s more powerful Ingenic XBurst chip for a slower, more power efficient MIPS chip that lacks a GPU: the homegrown Imagination cXT200. Other major changes include better wireless support and new MikroBus Click and Raspberry Pi compatible expansion interfaces. A FlowCloud API is available for cloud-based IoT device management. The above prices include two wireless “Clicker” carrier boards and three Click sensor modules.

Voted as the most requested board among those we omitted in last May’s survey, the Inforce 6410 is aimed primarily at the commercial market, but has also attracted makers who like the combination of a powerful multimedia SoC and an open platform. The 6410Plus board that arrived in June updates the original, bringing new robotics and IoT focused features like GPS, MIPI-CSI, MIPI-DSI, a beefier 12V power supply, a slimmer, 16mm profile, and a new 34-pin PAC expansion header. The 100 x 70mm Pico-ITX board continues to run Linux or Android on the Snapdragon 600, which combines four Cortex-A15-like, 1.7GHz Krait cores with an Adreno 320 GPU and other coprocessors. Inforce has replaced the LVDS interface with dual MIPI-DSI interfaces that join the pre-existing micro-HDMI port. Other features include GbE, microSD, SATA, WiFi, BT, and three USB ports, including an OTG model.

Price — $74

The Odroid-XU4 replaces the Odroid-XU3, which came in sixth place in our hacker board survey, and was recently discontinued along with the earlier Odroid-U3. The XU4 has the same octa-core Exynos5422 and Mali-T628 GPU as the XU3, but costs less than half the price. Along with other enhancements, this more than makes up for the net loss in interfaces. The XU4 moves from 10/100 to 10/100/1000 Ethernet, and adds a 12-pin GPIO header in addition to the previous expansion connector. Hardkernel has removed the DisplayPort, leaving you only with an audio-ready HDMI port. The USB 3.0 OTG port has morphed into a second USB 3.0 host port, and there’s only one USB 2.0 port instead of four. There’s no longer an audio codec or jack, so you’re dependent on HDMI, USB, or I2S for sound. As before, there’s an option for a USB-based SATA 3 module, I/O board, and various wireless options.

The Raspberry Pi Zero shocked the embedded world in November with a ground-breaking $5 price. Even when factoring in $5 to $25 more to add various cables and adapters, it’s a heck of a deal, especially if you can benefit from the compact, 65 x 30mm footprint. The Zero upgrades the same ARM11 processor found on the Pi A+ and B+ to 1GHz speed, yet it seems more like a follow-on to the COM-like, $30 Raspberry Pi Compute Module. The Zero will likely see duty as much in small-run manufacturing as it will for casual home hacking. The tiny 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. Missing are all the USB ports, DSI and CSI ports, and audio jacks found on the Pi 2.

The aging Wandboard remains popular (#17 in our May survey) thanks in large part to its still lively open board community, which churns out frequent software updates, such as its end-of-year Android Lollipop release. The Wandboard is designed as a modular, sandwich-style, COM+baseboard assembly featuring a replaceable compute module. Features include dual microSD slots, analog and SPDIF audio, plus Gigabit Ethernet, 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.
