The ESP32-C3 Mini Development Board is an ultra-compact, thumb-sized internet-of-things (IoT) microcontroller designed for small-scale smart devices. Shifting away from legacy architecture, it is powered by an advanced open-source 32-bit RISC-V single-core processor. It integrates full 2.4 GHz Wi-Fi and Bluetooth 5.0 (LE) into a microscopic, single-sided PCB footprint. Outfitted with a modern USB Type-C connector, it is highly optimized for ultra-low power consumption, making it the premier choice for wireless wearables, compact edge sensors, and smart keychains.
✨ Key Features
- Next-Gen RISC-V Architecture: Driven by a modern, single-core 32-bit RISC-V open standard instruction-set processor clocking up to 160 MHz.
- Upgraded Bluetooth 5.0 (LE): Supports long-range and high-throughput Bluetooth 5.0 Low Energy mesh configurations for low-latency pairing.Â
- Microscopic Space-Saving Profile: Features a miniature single-sided layout that lets you mount the controller flat onto other carrier boards or fit it into tight enclosures.Â
- Extreme Battery Efficiency: Draws an exceptionally low current of just ~43µA during deep-sleep states, maximizing battery-powered life cycle runtimes
