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.
The big chip has 2 number one pin markings
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.
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.

"Our favorite thing about PCBWay has to be their shared projects. This week we'd like to highlight the one about using old cat6 for trapping and the best places to scavenge for it"
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.
The wiring is consistent (no ghost/empty wires) so likely not AI.
Perhaps a board from some form of drone that fits in the nose cone?
Edit: Never mind, saw the comment about the #1 pin.
It's AI. The top chip is rectangular, but QFP packages are all square. The bottom chip has two pin 1 markings (the board does too). There's also some weird interaction between the ground plane and the two capacitors on the right
Duh, it's obviously from a smart spear that stopped working because it was part of a bot net.
