Earlier this month I covered Jonathan Clark's effort to reverse-engineer the Pi Zero 2 W, and just yesterday, I discovered TubeTime reverse-engineered the Compute Module 5.
Both are graciously sharing their schematics and process on GitHub:
jonny12375/rp3a0 for the Zero 2 W / RP3A0
schlae/cm5-reveng for the CM5 / RP2712
Raspberry Pi shares limited board schematics, but sometimes—especially when digging into some esoteric edge case for a carrier board, or in Jonathan's case, desoldering all the chips and building a Pi Zero 2W into a Pico form factor PCB—you need more.

Well, in both cases, I realized after the fact I was sitting on some highly detailed Lumafield scans, which I had planned on making a video going through at some point for a project I'm working on this year. But that data would've helped in both projects (at least mildly). It's not as good as hand-sanding a PCB and getting high resolution scans, but it is especially helpful in getting a 'look inside' 3D representation of the complete board.
So, along with a video on my 2nd YouTube channel today, I'm releasing all the Lumafield scans of the modern Raspberry Pi lineup (excluding the larger keyboard form factor Pis, like the Pi 400 and Pi 500... maybe I can get to those too, someday).
Here's the video:
And here are links to all the Lumafield scans in their Voyager tool, so you can play with them and dig into the Pi internals yourself:
HUGE thanks to Lumafield for helping me produce these scans.
