 * The board definitions in this file are valid for the Espressif

 *
 * Since the number of GPIOs and their possible uses on the ESP32-H2 are quite
 * limited, these board definitions can also be used for most other
 * ESP32-H2 boards. Any modifications required for specific applications
 * can be overridden by \ref esp32_application_specific_configurations
 * "application-specific board configuration".

 * used as button during normal operation. Since the button connects GPIO9 pin
 * to GND, the button signal is inverted, i.e., pressing the button will give a
 * low signal.
