BIAONU

BIAONU is a label for resin printer repair electronics: 405 nm UV LED boards, UV LED driver boards, power supplies, and LCD replacement kits. Printer makers rarely sell these units at retail, so a repair often comes down to BIAONU or nothing.

The brand has no website and no verifiable company behind it — everything moves through marketplace stores. Our catalog lists nine BIAONU parts for Elegoo machines, from the Mars 4 UV LED board to the Jupiter LED array and the Saturn 3 Ultra power supply. They drop into the stock mounts, but check the connector type and LED count against your own board before ordering.
