Choose Your Favorite Open Source SBC, Enter to Win Prizes

ArduinoTreWhen I began researching's third annual Top 10 open source SBC board feature, it quickly became clear that so many new boards had shipped since our last Top 10 in August 2013, any personal judgment would be highly arbitrary. So in the spirit of self-serve consumerism and general laziness, I am passing the hard work on to you. Together with (see their article here), has set up a survey on SurveyMonkey with 32 open spec single board computers that fit our fairly broad requirements.

Pick your top three products and answer a few questions about what you're looking for in a hacker board, and enter the drawing for a chance to win cool Tux, embedded Linux, and Android gear. Five randomly selected winners will receive a T-shirt, sweatshirt, hat, mug, or USB drive.

CLICK HERE TO TAKE THE SURVEY NOW! (Or scroll down to the embedded survey, below.)

After the 10-day survey is completed, we'll compile our official Top 10 Open SBC list, and analyze the results for trends. After filling out the brief survey on SurveyMonkey, enter your email address at the end. The email address will only be used in case you're chosen as a winner. (You must be 18 years or older, and no purchase is necessary to enter or win. Void where prohibited.)

We are particularly interested in hands-on experience, but we also realize that relatively few people have used more than a few of these boards, so it's not a prerequisite. Even if you've only learned about some of these boards from the press, from word of mouth, or getting a demo at a friend's house, a store, or a tech show, we'd like to hear from you. Also, if your favorite board isn't on the list, you can add it in the comments section, and we will make note of those. Farther below, we offer brief summaries of the 32 boards, with links to product pages. More information can be found at LinuxGizmos, which has covered most of these boards over the last year.

HummingBoardThe SBCs on our list are all shipping, even if only recently. They must offer open source Linux and/or Android images or offer links to other free sources. The projects must offer schematics and other hardware reference materials for at least most of the board's features and components. At a minimum, licensing should enable third parties to build products at least for small runs of non-profit applications.

It's also essential that the boards are backed up with at least some community website features, with a forum or something similar, where users can ask technical questions and exchange tips. Ideally, there should be additional documentation, tutorials, and other resources.

The boards need to supply a few real-world ports at a minimum, as opposed to a computer-on-module (COM) that requires a baseboard. On the other hand, a growing number of new contenders are modular COM/baseboard combos sold as integrated SBCs. Some of these SBCs are also available with enclosures as miniPCs, but they must also be sold as boards.

For space reasons, our summaries below do not always list OS support. The vast majority, however, support Android and one or more Linux distros. A few are Linux only, and some are more oriented toward Android, but also support Linux.

Also note that after the name of the board, we often list more than one vendor name. This is because open SBCs are often collaborations between manufacturers, open source projects, and distributors. We list distributors when they appear to be the sole distributor of the product. The listed prices are the lowest we found, but forgive us if we did not find the ultimate bargain price. Prices change over time, and in some cases vary significantly depending on the distributor.

Finally, you may have noted that some hot new boards you've read about are not on the list posted farther below. That's because they haven't shipped yet. Perhaps on next year's list we'll see products like:

Arduino TRE -- Arduino's first SBC to run a full Linux distro (on a TI Sitara AM335x SoC) along with the usual Arduino goodies
HummingBoard -- SolidRun's Raspberry Pi clone with modular COM/baseboard setup, aimed at its CuBox developers
Logi -- ValentFX SBCs that combine FPGA circuitry with plug-in Raspberry Pi or BeagleBone Black boards used a COMs
MinnowBoard Max -- Intel's $99, second-gen hacker board featuring a new Atom E3800 and Arduino compatibility
Red Pitaya -- Xilinx Zynq ARM/FPGA based SBC for open source Linux-based measurement and control
Warpboard -- Freescale's tiny, single-core i.MX6 based SBC, designed for wearables and Internet of Things (IoT) devices.
