Detailed Description
Board definitions for ESP32-H2-DevKitM-1 boards.
The board definitions in this file are valid for the Espressif ESP32-H2-DevKitM-1 board the ESP32-H2-MINI-1x module.
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 application-specific board configuration.

Default button GPIO pin definition.
ESP32-H2-DevKitM-1 boards have a BOOT button connected to GPIO9, which can be 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.
