VMARC RK3288 SOM is a standard SMARC SOM design with Rockchip RK3288 SoC, which is designed by Vamrs.
Specification:
- Rockchip RK3288
- PMIC: RK808
- SD slot, 16GiB eMMC
- 2xUSB-2.0, 1xUSB3.0
- USB-C for power supply
- Ethernet, PCIe
- HDMI, MIPI-DSI/CSI, eDP
Add initial support for VMARC RK3288 SOM, this would use with associated carrier board.
