The following item is a prototype PlayStation 5 motherboard, this version which is EDM-BR10 wasn't released to the public.
EDM-BR10 appears to be the diskless motherboard, another such board named EDM-AR10 exists, which appears to be the disk based version.
Our board appears to be a reject, and was as such disposed off in e-waste, it then suffered from water damage along with damage to the motherboard rendering it unrepairable at this time.
The EDM-BR10 board still retains a PVT (Product Validation Testing) WiFi chip.
