Introduction

ESP32-C3-DevKitC-02 is an entry-level development board based on ESP32-C3-WROOM-02, a general-purpose module with 4 MB SPI flash.

This board integrates complete Wi-Fi and Bluetooth LE 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.
