### Board Configuration {#esp32s3_devkit_board_configuration}
ESP32-S3-DevKit boards have no special hardware on board with the exception
of a single pin RGB-LED that uses a special bit-oriented protocol to
control the RGB-LED by 24-bit RGB values which is not supported yet.
of a single pin RGB-LED.
All GPIOs are simply broken out for flexibility. Therefore, the board
configuration is the most flexible one which provides:
