WIP Raspberry Pi CM4 module adapter for MNT Reform. Made today with KiCAD on my Reform in the home office. Still needs a bunch of components for the STDP2600 HDMI->eDP converter.
An interesting exercise.
Pros of CM4: Quad Cortex-A72, 8GB RAM available; potentially higher OpenGL versions and Vulkan possible (not tested by me yet);
Cons: No USB3.0. Only 1x PCIe. DSI undocumented. Might need active cooling.
