Hardware#

OpenBikeComputer uses the Nordic nRF54LM20 development kit. It uses a 240 × 320, 64-color Sharp LS021B7DD02 reflective memory LCD.

The board crate defines the pin map, sensor connections, storage transport, build flags, and flash procedure: firmware/obc-fw-nrf54l.

The display protocol defines the panel waveform and the FLPR scan sequence.

The repository does not contain production schematic, PCB, or enclosure sources.
