# Huawei R48xx: mapping the power supplies' CAN protocol

> Huawei R48xx documents the CAN communication of Huawei 48 V power supplies, including 29-bit identifier fields, status commands, registers and software address negotiation between units. The author combines tests on R4830S1, R4850G2 and R4850G6 with other documentation. The repository also records connector pinouts and printable enclosure models.
