From the project
Experimental baseboard supporting System on Modules with Raspberry Pi CM4/CM5 pinout
This project contains open hardware design files for a baseboard supporting System on Modules (SoMs) with Raspberry Pi Compute Module rev. 4.0 (CM4) pinout. The baseboard is also electrically compatible with Compute Module rev. 5.0 (CM5). Please note that the pins associated with CAM0 and DSI0 on the CM4 module were changed to USB 3.0 ports on the CM5 module. Please refer to the schematics of the baseboard and respective compute modules for details.
