Snapdragon 820 lands on an Android Pico-ITX SBC

Feb 17, 2017 — by Rick Lehrbaum 3,933 views

[Updated Feb. 21] — Inforce Computing’s model 6640 Pico-ITX SBC is based on a Snapdragon 820 SoC and features 4GB RAM, 4K video, WiFi/BT/GPS wireless, GbE, SATA, and Android 7.

Inforce Computing has launched what it claims is the “first commercial single board computer” based on Qualcomm’s Snapdragon 820 processor. The $289 Pico-ITX form factor board targets “advanced, high-end embedded devices” with applications including “virtual/augmented reality, healthcare, gaming, 4K video collaboration, cameras, and Internet of Things,” says the company.

This new Inforce 6640 SBC joins several earlier Inforce Pico-ITX models that are similarly based on Qualcomm Snapdragons, including the Inforce 6410 (Snapdragon S4 Pro), Inforce 6540 (Snapdragon 805), and Inforce 6410Plus (Snapdragon 600). Computer-on-modules based on the Snapdragon 820 that we’ve covered include the eInfochip Eragon 820, Inforce’s 6601 Micro SOM, and the Intrinsyc Open-Q 820.

Inforce 6640 details


The Inforce 6640’s Snapdragon 820 SoC integrates four 14nm FinFET fabricated “Kyro” cores that roughly mimic the ARMv8 Cortex-A72 design. The Kryo cores — two at 2.GHz, and two at 1.6GHz — offer up to twice the performance and twice the power efficiency of the Cortex-A57 cores on the Snapdragon 810. There’s also a 624MHz Adreno 530 GPU with up to 40 percent improvement in graphics over the previous Adreno 430, according to Qualcomm. An upgraded Hexagon 680 DSP and a 14-bit Spectra image signal processor (ISP) are also contained within the SoC.

The 100 x 70mm board’s Snapdragon 820 SoC is accompanied by 4GB of LPDDR4 soldered-on RAM as well as 64GB of speedy UFS 2.0 flash memory. The SBC integrates a pair of pre-certified Qualcomm wireless modules — a QCA6174A for dual-band 802.11ac WiFi along with Bluetooth 4.2 LE, plus a WGR7640 for GPS/GNOSS functionality. There’s also an Atheros 8151-based Gigabit Ethernet interface. The board’s product page currently shows a 0 to 55°C “commercial” operating temperature range, despite the fact that most of Inforce’s SBCs and COMs have in the past supported a 0 to 70°C “industrial” range.

Like Inforce’s earlier Pico-ITX SBCs, the Inforce 6640 includes a 34-pin “PAC” expansion header with signals including I2C, SPI, UIM, UART, serial console, and 12x GPIOs. Inforce accessories that support the Inforce 6640 include the ACC-1S70 PoE card and the ACC-1H70 21MP camera card (shown at the right). The latter integrates a Sony IMX230 sensor that is capable of capturing 4K video and 21MP photographs, says Inforce.

    Please let us know when they release “real” linux for it. It’s disappointing that it’s Android-only, as they normally have some form of conventional linux available for their boards.

    • Keith Fleer says:

      Hi Phil, we currently have a working Linux release that is undergoing testing internally. We expect it to be ready for full commercial release by the end of the quarter (around end of March). For customers who have a more urgent need we can give early access, but we didn’t want to make a formal announcement until we’ve added the most popular features/drivers and put it through a full bout of testing to ensure it’s stable for consumer devices.

      • Phil Endecott says:

        It’s now August and I still see no mention of anything other than Android on the website :-(

        • Keith Fleer says:

          Hi Phil, our Linux build is now product-ready and available for download & installation to customers who purchase and register a board. We haven’t yet added a product SKU to our shelf stock that has Linux pre-loaded, which is why you don’t see it mentioned on the website. We’re working on updating our materials so they reflect its availability.

          • Phil Endecott says:

            It’s now December and the website still says “An Ubuntu/Debian Linux based BSP would soon be made available and please stay tuned to our website for an announcement on this package”

  2. RedDevil says:

    Hi – just wondering what “full commercial release” means for linux? Also there is some confusion over the USB port configuration (text above differs from web site and text and diagram on web site are different) – some clarification would be helpful. Dick

    • LinuxGizmos says:

      The USB port configuration appears to be our error. Double-checking the board’s page on Inforce’s website, there appear to be just two ports, as indicated on the function diagram (above). Thanks for catching that mistake!

      Regarding “full commercial release” I think that means it has passed all of the company’s qualification tests and is considered solid on the board, whereas as mentioned in Keith Fleer’s comment, it’s possible to get early access either now or soon. You can email the company if you need more specifics.

      • LinuxGizmos says:

        I think the diagram is correct, and have edited this post’s specs summary accordingly. But I’ll check with Inforce.

    • LinuxGizmos says:

      Inforce had the USB types swapped in their block diagram, and has supplied a corrected image, which now appears above. The two USB ports are 1x USB 3.0 Host and 1x USB 2.0 Host/OTG, as had been listed on their product page.
