Detailed Description
Board definitions for ESP32-S3-DevKit boards.
The board definitions in this file are valid for Espressif ESP32-S3-DevKitx boards that use one of the following modules:
- ESP32-S3-MINI-1x module (ESP32-S3-DevKitM-1 board)
- ESP32-S3-WROOM-1x module (ESP32-S3-DevKitC-1 board)
- ESP32-S3-WROOM-2x module (ESP32-S3-DevKitC-1 board)
where x stands for the module version with and without U (external antenna connector).
Any modifications required for specific applications can be overridden by application-specific board configuration.

◆ BTN0_MODE
| #define BTN0_MODE GPIO_IN_PU |
◆ BTN0_PIN
| #define BTN0_PIN GPIO0 |
Default button GPIO pin definition.
ESP32-S3-DevKit 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.
