The funny thing is that that board is actually designed to be arrowhead-shaped, not just a shard sawn off a larger PCB. I wonder what it came from (assuming it's real)?

    I noticed the same thing. Maybe it’s AI. I don’t see any inputs or power source and there’s no indication that there’s anything big enough on the other side to be either.

    Could be a car key fob maybe? CR2032 and buttons could fit on the backside

    Maybe, but it would be huge. Most key fobs I’ve seen don’t need mounting screws either. I’m not sure about the battery holder, but any buttons on the other side would likely run through the pcb. I don’t think contact solder would be strong enough for repeated use. There would also be traces somewhere that come from the other side to the controller.

    I don't see any merging traces or other aspects of it that don't make sense when looking at the board holistically, so I don't think it's AI. Edit: another commenter pointed out two "pin 1" marks on the biggest chip, so never mind, it's AI. Fuck.

    With two microchips with that many pins (maybe a 4+ layer PCB?), it looks too complicated to be a key fob. It also has what looks like a 5-pin header for programming.

    It does look close to PCBs you'd see in random key fobs but I think solid chance it's a prop (or AI). If you look close and of course we do only see one side but a lot of the things you'd expect to see are missing. What could this do, how does it interact or connect to things, whats up with those traces and why are they going there, who made this and why is nothing labeled? None of that is definitive, but it's weird to have that many questions like those on a real PCB.
