* ESP32-C3-DevKitx boards that use one of the following modules:
|
|
*
|
|
* - ESP32-C3-MINI-1x module (ESP32-C3-DevKitM-1 board)
|
|
* - ESP32-C3-WROOM-02x module (ESP32-C3-DevKitC-02 board)
|

|
|
* Since the number of GPIOs and their possible uses on the ESP32-C3 are quite
|
|
* limited, these board definitions can also be used for most other
|
|

|
|
* can be overridden by \ref esp32_application_specific_configurations
|
|
