/**
 * @brief   Default button GPIO pin definition
 *
 * ESP32-S3 WT32-SC01 Plus boards have a BOOT button connected to GPIO0, which can be
 * used as button during normal operation. Since the GPIO0 pin is pulled up,
 * the button signal is inverted, i.e., pressing the button will give a
 * low signal.
