The ESP32-C3 WROOM Development Board is an entry-level development board based on ESP32-C3-WROOM-02, a general-purpose module with 4MB SPI flash. This board integrates complete WiFi and Bluetooth LE functions.

The Espressif ESP32-C3 is the next version of the popular ESP32 Bluetooth® and WiFi enabled module. This module features a single core, RISC-V-based processor with WiFi and Bluetooth LE 5.0 radios built into the SoC. The module features a PCB antenna and castellated plated pins for surface-mount soldering. This variation has 4 MB of on-board SPI flash and is the 85 °C temperature tolerant version.

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. Other features include a boot button, reset button, and an addressable RGB LED.
