DFRobot ESP32-C3-DevKitC-02 Development Board is based on the ESP32-C3-WROOM-02 general-purpose module with 4MB SPI flash. The 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. Connect peripherals with jumper wires or mount the ESP32-C3-DevKitC-02 on a breadboard.
