There are three mutually exclusive ways to provide power to the board:
|
||||
|
||||
- Micro USB port, default power supply
|
||||
- 5V and GND header pins
|
||||
- 3V3 and GND header pins
|

- ESP32-C3-MINI-1 is a general-purpose Wi-Fi and Bluetooth LE combo module that comes with a PCB antenna. At the core of this module is `ESP32-C3FN4 <https://www.espressif.com/en/products/socs/esp32-c3>`_, a chip that has an embedded flash of 4 MB. Since flash is packaged in the ESP32-C3FN4 chip, rather than integrated into the module, ESP32-C3-MINI-1 has a smaller package size.
