Introduction

Jumpstart wireless IoT projects with this feature-packed ESP32-C3 development board. Combining dual-band WiFi (2.4GHz) and Bluetooth LE 5.0, this breadboard-ready microcontroller delivers ultra-low power consumption (3.0-3.6V) with 160MHz RISC-V core performance – perfect for smart home devices, wearables, and industrial sensors.


Wireless Connectivity Made Simple

The ESP32-C3-WROOM-02 module provides complete RF stack integration, supporting both station and AP modes for flexible network topologies. With PCB antenna and -40°C to 85°C operating range, it reliably handles harsh environments.


Optimized for Rapid Prototyping

All 21 GPIO pins (including 6x 12-bit ADC channels) are broken out to standard 2.54mm headers. The USB-to-UART bridge (3Mbps) enables one-click programming via Micro-USB port, while the built-in RGB LED offers visual debugging.


Future-Proof RISC-V Architecture

Powered by a 32-bit RISC-V core, this board outperforms traditional ARM chips with 400KB SRAM + 384KB ROM, handling complex edge computing tasks. The 4MB SPI flash provides ample storage for OTA updates.
