Archive: https://archive.today/u3F0R From the post: >>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.
