Reverse engineered Raspberry Pi Compute Module 5
This is the reverse engineered schematic and layout for a Raspberry Pi Compute Module 5. It's not meant to be fabricated--critical signal integrity parameters aren't correct, it's not 100% faithful to the original, the footprints aren't a perfect match, and the bill of materials is not reverse engineered. You also won't be able to obtain most of the chips since they are custom for this design or only available to large customers, not through a distributor.
