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.
This PS Vita Kiosk unit was used internally by SCEA in the United States, it was used to test game builds before release and was found on eBay via an e-waste shop.
Due to it being used to test game builds, this item is under our developer systems section.
