More photos in the comments. Is it supposed to be connected to the motherboard? I found it in the case. It wasn't connected. I think that the backside is some sort of thermal patch. I can tell that it's not a camera but I'm very confused and the connection reminds me of more of a laptop or phone connection not something you would see in a PC. The data matrix contains the same text as the white sticker.
This is wild. It almost looks like a tiny speaker, but the cable is strange for that. I don’t think it’s a thermocouple, - cable looks like it has at least 4 wires in it?
It seems to have 12
So it’s gotta be some kind of sensor array or something then. Speakers and whatnot wouldn’t have more than 2 or 3.
