Impressive!
Out of lack of understanding: what does this new knowledge allow? Will it allow open-source developers to write better drivers? Or does it allow the making clones? Or nothing in particular?
This is a PCB layout and board schematics. So this helps component level repair (uneconomical in first world) and diagnosing some of the weirder failures or hardware limitations. It also helps make a stronger case that RPI Foundation should have released this in the first place.
You could use this to make clones - but only if you could source at least the BCM2712 SoC, preferably RP1 too. I can't imagine that happening in practice.
This helps placing an RP1 on a PCI-E card.
Isn't this the same as previous? https://news.ycombinator.com/item?id=45018509
Those are lumafield scans.
This is the old analog CT method: sanding
No, the previous post focused more on the Lumafield scans of the Raspberry Pi boards. This one is about reverse engineering the schematics of the CM5.
Different project, one which was referenced in the post for that thread
The elephant in the room: Why is it not Open Source Hardware to begin with?
Discourage cloning.
NDA's with Broadcom.
Non-answer. BCM is far from the only vendor.
Broadcom has its hand so far up RPI Foundation's ass they might as well be conjoined.
