From the project
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.

CM5RevEng: common questions
What microcontroller does the CM5RevEng use?
The CM5RevEng is built around the BCM2712, from the Raspberry Pi family.
How big is the CM5RevEng PCB?
The CM5RevEng measures 55 × 40 mm, has 10 copper layers and is 1.2196 mm thick.
How many components are on the CM5RevEng?
417 components, from 66 distinct parts. The full bill of materials is listed on this page.
Where can I download the CM5RevEng design files?
From the schlae/cm5-reveng repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the CM5RevEng design in my own project?
The repository has no license, so all rights stay with schlae. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the CM5RevEng without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
