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 10.1" Open Frame
Add support for it.
