Detailed Description
Board specific definitions for generic ESP32-WROOM-32 boards.
This configuration can be used for a large set of ESP32 boards that use an ESP32-WROOM-32 module and simply break out all GPIOs to external pads without having any special hardware or interfaces on-board. Examples are Espressif's EPS32-DEVKIT or NodeMCU-ESP32S and a large number of clones.
For detailed information about the configuration of ESP32 boards, see section Common Peripherals.
- Note
- Most definitions can be overridden by an application-specific board configuration.

Default button GPIO pin definition.
Generic ESP32 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.
