In cases where the board does not respond to the remote, verify the IR sensor wiring. The pinout for the IR header is usually VCC, IR, GND, R-LED, and G-LED. Ensure these match the pins on your specific sensor module.
Switch between 6-bit, 8-bit, and 10-bit color tracking to match your physical panel specs.
