ESP32-C3 SuperMini Dev Board V2

Introducing the ESP32-C3 SuperMini V2, a compact yet powerful development board built around the advanced ESP32-C3 microcontroller. Ideal for developers and enthusiasts, this board combines the capabilities of the ESP32-C3 with a sleek and space-efficient design, perfect for IoT and wireless applications.

The ESP32 SuperMini features the Espressif ESP32-C3 WiFi/Bluetooth dual-mode chip, which is a 32-bit RISC-V CPU with an integrated floating point unit (FPU) for 32-bit single precision operations. This enables powerful computing performance and excellent RF capabilities, supporting IEEE 802.11 b/g/n WiFi and Bluetooth 5 (LE) protocols. The board includes an external antenna for enhanced signal strength, 11 digital I/Os usable as PWM pins, 4 analog I/Os for ADC functions, and supports multiple serial interfaces, including UART, I2C, and SPI. It also features convenient on-board buttons for reset and bootloader mode, making it a versatile tool for a wide range of projects.
