Kaynes’s “SKATE-212” SBC runs Android Nougat or Linux on a quad -A7 Snapdragon 212 with WiFi, BT, GPS, LAN, IMU, dual MIPI-CSI, and a 7-inch touchscreen.

Long-time Qualcomm partner Intrinsyc delivered the first SBC built around Qualcomm’s Snapdragon 212 SBC back in May with its $595 Open-Q 212. Now, as noted first by CNXSoft, Intrinsyc has some cheaper competition from a SKATE-212 SBC development kit from India-based Kaynes Technology that has gone on pre-order for only $349. The kit is designed for “industrial, medical, IIoT, mission critical, and surveillance verticals.”

The Snapdragon 212 is a minor update to Qualcomm’s Snapdragon 210 that was released last year with a faster, up to 1.3GHz clock rate. The quad-core, Cortex-A7 SoC is paired with an Adreno 304 GPU. As with the Intrinsyc board, Android 7 “Nougat” is standard, and Linux is available on request.


Open-Q 212

The Snapdragon 212 SoC offers HD video decode support, although the Open-Q 212 supports only [email protected] H.264/H.265 (HEVC or AVC) playback and H.264 AVC capture. This appears to be the same with the SKATE-212, which notes only that “HDMI supports max 720P only” and that the HDMI and LCD interfaces can’t be used simultaneously. Unlike the Open-Q, the SKATE-212 comes standard with a 7-inch capacitive touchscreen.

The SKATE-212 measures 90 x 70mm, compared to the 120 x 120mm, Nano-ITX based Open-Q 212. No temperature range was listed. The SBC supplies the same standard memories and microSD slot as the Open-Q, but unlike Intrinsyc, Kaynes offers expansion options of up to 2GB RAM and 16GB eMMC flash.

The SKATE-212 provides a second 2-megapixel camera interface in addition to the 8-megapixel interface provided by the Open-Q 212, and an 8-megapixel camera accessory is said to be coming soon. The SBC lacks the Intrinsyc board’s extensive audio I/O support, and there’s no mention here of support for Qualcomm’s Voice Activation, Voice+, or Fluence audio technologies. You do get some basic audio features, however.

There are no antenna connectors listed for the WiFi and Bluetooth BLE, but Kaynes adds GPS support, with optional GLONASS. Like the Open-Q board, the SKATE-212 provides a Fast Ethernet port.

There are only two USB 2.0 hosts instead of four on the Open-Q board, and there’s no serial port. On the other hand, Kaynes adds a micro-USB console port and micro-USB device port. However, you can’t use the device port when the Ethernet port or USB host ports are in operation.

With its 40-pin connector, the SKATE-212 appears to have more expansion I/O that its rival. Battery power is similarly optional on this 12V board.
