The single-board hardware for CycleSync: a compact, sealed, handlebar-mounted device that plays GPS-time-synchronized audio across many units, with an optional live-DJ line-in. This repo turns the bench-validated breakout-board prototype into one manufacturable, ruggedized mixed-signal PCB.
A single RP2354-class MCU presents as a composite USB device (USB Audio out + in + MIDI) to the phone host, runs the I²S audio domain as master, reads a GNSS module over UART + 1PPS for absolute timing, and configures the audio ADC and USB-PD controller over I²C.
