PX30.Core is an EDIMM SOM based on Rockchip PX30 from Engicam.
General features: - Rockchip PX30 - Up to 2GB DDR4 - eMMC 4 GB expandible - rest of PX30 features
PX30.Core needs to mount on top of Engicam baseboards for creating complete platform boards.
Possible baseboards are, - EDIMM2.2 - C.TOUCH 2.0
Add support for it.
