The ESP32-C3 SuperMini Dev Board V2 is a compact and powerful development board designed for next-generation IoT and wireless applications. Featuring the ESP32-C3 RISC-V microcontroller, it provides Wi-Fi 4 and Bluetooth 5.0 Low Energy in a single-core 32-bit architecture, ideal for low-power and secure embedded systems.

This upgraded V2 version includes a native USB-C port, removing the need for external USB-to-serial adapters. It supports CDC, DFU, and USB HID, enabling rich USB device development in addition to wireless use.

With 4MB of onboard flash, up to 21 GPIO pins, multiple digital interfaces (SPI, I2C, UART, PWM, ADC), and ultra-low power modes, the ESP32-C3 SuperMini V2 is perfect for developers building smart home devices, BLE peripherals, wireless sensors, and portable electronics.

Fully compatible with Arduino, ESP-IDF, and MicroPython, this board is a favorite among developers looking for small, powerful, and affordable embedded solutions.
