comprised of the i.MX8M Plus based gw702x SoM and the gw82xx
baseboard featuring:
- i.MX8M Plus SoC
- LPDDR4 DRAM
- eMMC FLASH
- Gateworks System Controller (GSC)
- microSD (1.8V/3.3V Capable)
- panel status bi-color LED
- pushbutton switch
- fan controller with tachometer
- USB Type-C connector
- PCIe switch
- 2x GbE RJ45 connectors
- multi-protocol RS232/RS485/RS422 Serial ports
- 2x Flexible Socket Adapters with SDIO/UART/USB/PCIe
(for M.2 and miniPCIe expansion)
- 2x isolated CAN
- GPS
- accelerometer
- magnetometer
- off-board connectors for: SPI, GPIO, I2C, ADC
- Wide range DC power input
- support for 802.3at PoE (via adapter)
Add support for it by providing its device-tree.
