Description
The ESP32-C3-DevKitC-02 serves as an introductory-level development board, built around the ESP32-C3-WROOM-02, a versatile module featuring a 4 MB SPI flash. This development board seamlessly incorporates comprehensive Wi-Fi and Bluetooth Low Energy capabilities.
For convenient interfacing, the majority of the I/O pins are exposed on the pin headers, located on both sides of the board. Developers have the flexibility to connect peripherals using jumper wires or securely position the ESP32-C3-DevKitC-02 onto a breadboard.
