Due to the lack of an official public datasheet, the pinout details are derived from reverse engineering, circuit schematic analysis, and electrical measurements taken from working units. The following table outlines the known functions, reference designators, and in-circuit static voltage readings for a properly functioning device.
Write 0x00 to LED Mode 0 to enable PWM, then set fade-in/out registers (0x20–0x2F). The hardware automates the breath waveform. highway09a ic datasheet
