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.

Looks like a complex board. Who was the board design outsourced to and who did the high speed trace consulting?

The elephant in the room: Why is it not Open Source Hardware to begin with?

    The number of people who care is small enough not to affect any outcome.

      The amount of people that design and repair electronics is significantly smaller than the people that use electronics, that doesn't mean RasPi should ignore them. They boast opensource development, but seem to be working counter to that.

      It makes is substantially easier to work with known design docs, and RasPi want people to use their hardware in embedded applications.

      It's not like you can replicate their hardware with just the schematic. Its awesome to see other filling the gap, but its a gap that has no need to exist.

        I agree that they shouldn't be ignored, but... how to compel companies to share schematics, in the absence of enlightened legislation?

          The original mission was to get kids into computing with a low cost board, something akin to the C64 back in the 80s. But apparently that is only as user and not as a creator. I'd argue that getting kids into computing at the hardware level is even more important now.

          But I think in some small part the RPi Foundation has captured itself and turned into a for profit company where the original mission takes a back seat.

    NDA's with Broadcom.

      Non-answer. BCM is far from the only vendor.

      • ACCount37 7 hours ago

        Broadcom has its hand so far up RPI Foundation's ass they might as well be conjoined.

        • mouse_ 5 hours ago

          True, this is the real answer.

Isn't this the same as previous? https://news.ycombinator.com/item?id=45018509

    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.

    Those are lumafield scans.

    This is the old analog CT method: sanding

    Different project, one which was referenced in the post for that thread

ten (10) layer board! :o Following twitch stream where TubeTime was doing it live gave some interesting insights, afair it did look like layout was done by more than one person and some things seemed to suggest time was more valuable than optimizing for less layers.
