|
|
This user guide will help you get started with ESP32-C3-DevKitC-02 and will also provide more in-depth information.
|
|
|
|
ESP32-C3-DevKitC-02 is an entry-level development board based on `ESP32-C3-WROOM-02 <https://www.espressif.com/sites/default/files/documentation/esp32-c3-wroom-02_datasheet_en.pdf>`_, a general-purpose module with 4 MB SPI flash. This board integrates complete Wi-Fi and Bluetooth® Low Energy functions.
|
|
|
|
Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-C3-DevKitC-02 on a breadboard.

Power Supply Options
|
|
^^^^^^^^^^^^^^^^^^^^
|
|
|
|
There are three mutually exclusive ways to provide power to the board:
|
|
|
|
- Micro-USB Port, default power supply
|
|
- 5V and GND pin headers
|
|
- 3V3 and GND pin headers
|
|
|
|
It is recommended to use the first option: Micro-USB Port.

.. [1] P: Power supply; I: Input; O: Output; T: High impedance.
|
|
.. [2] GPIO2, GPIO8, and GPIO9 are strapping pins of the ESP32-C3 chip. These pins are used to control several chip functions depending on binary voltage values applied to the pins during chip power-up or system reset. For description and application of the strapping pins, please refer to Section Strapping Pins in `ESP32-C3 Datasheet`_.
