[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.
