ESP-32C3 SuperMini – Powerful, Ultra-Compact IoT Development Board
The ESP32-C3 SuperMini is a mini IoT development board built around Espressif’s ESP32-C3 Wi-Fi/Bluetooth dual-mode chip. Powered by a 32-bit RISC-V CPU with an integrated FPU for 32-bit single-precision computation, it delivers robust processing performance in an impressively small footprint. With outstanding RF capabilities, it supports IEEE 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE). The board also includes an external antenna to further strengthen wireless signal performance.
Designed with a compact, refined form factor and a single-sided SMD layout, the ESP32C3 SuperMini offers rich connectivity options: 11 digital I/O pins capable of PWM output, 4 ADC analog input pins, and support for UART, I2C, and SPI serial interfaces. It also features an onboard reset button and a bootloader mode button for easy development.
Combining powerful performance, low power consumption, and excellent value, the ESP32C3 SuperMini is ideal for low-power IoT devices, wireless wearables, and compact smart applications.
