ESP32-C3 SuperMini IoT Development Board with WiFi & Bluetooth 5.0

The ESP32-C3 SuperMini Development Board is a compact and efficient IoT development platform built around Espressif’s ESP32-C3 RISC-V 32-bit microcontroller. Designed for modern wireless applications, it integrates 2.4 GHz WiFi and Bluetooth 5.0 Low Energy, making it well suited for smart devices, automation systems, and portable electronics.

Despite its thumb-sized footprint, the board offers strong processing performance with a clock speed of up to 160 MHz, along with 4 MB flash memory, ample SRAM, and a wide range of GPIO options. It supports common communication protocols such as UART, SPI, and I2C, allowing seamless integration with sensors, displays, and peripheral modules.

The ESP32-C3 SuperMini is optimized for low-power operation, achieving ultra-low deep sleep current, which is ideal for battery-powered and energy-constrained designs. Power can be supplied via USB or an external 3.3 V–6 V source. An optional expansion board further enhances usability by adding Li-ion battery charging and extended GPIO access.

Compatible with Arduino IDE, ESP-IDF, and MicroPython, this board is suitable for both beginners learning embedded development and professionals building reliable IoT solutions.
