Description

The 7Semi ESP32-C3 Dev Board is a compact, breadboard-friendly development board engineered around the Espressif ESP32-C3FH4 chip—a 32-bit RISC-V single-core processor clocked at up to 160 MHz. With built-in 2.4 GHz Wi-Fi and Bluetooth 5 LE, this module provides an ideal balance of connectivity, power efficiency, and security.

The board integrates a USB Type-C port for power and programming, an onboard RGB status LED, and supports low-power operation modes, making it perfect for embedded wireless applications, sensor nodes, automation control, and rapid prototyping.
