Reverse Engineering ALL the Raspberry Pis

It's the month for Raspberry Pi reverse engineering, apparently! First I showed the Pi Zero 2W in a Pico form factor: https://www.youtube.com/watch?v=p7IvioiveOo And now @TubeTime has reverse-engineered the Compute Module 5! https://github.com/schlae/cm5-reveng I've decided to run through all the scans I recently did with Lumafield, for the benefit of anyone reverse engineering any of the other Pi models, and here they are, in all their glory! - Raspberry Pi 4 model B: https://voyager.lumafield.com/project/c50be82c-188c-4405-ac55-676a388d2122 - Raspberry Pi CM4: https://voyager.lumafield.com/project/ad315d0b-7143-4b3d-963d-2018a5314f1b - Raspberry Pi Zero 2 W: https://voyager.lumafield.com/project/fcbc8145-2873-4432-bfcc-29896cd440c9 - Raspberry Pi 5: https://voyager.lumafield.com/project/5f0cf35f-c5f1-4db0-a0f5-d06ecb9bc359 - Raspberry Pi CM5: https://voyager.lumafield.com/project/9a14818b-f9a7-49d1-b9c9-09e0560e1498 HUGE thanks to Lumafield for helping me produce these scans.
