ESP32C3SuperMini is an IoT mini development board based on the EspressifESP32-C3 WiFi/Bluetooth dual-mode chip. ESP32-C3 is a 32-bit RISC-VCPU, including FPU (Floating Point Unit), which can perform 32-bit single-precision operations: it has powerful computing capabilities. It has excellent RF performance supporting IEEE 802.11 b/g/n WiFi and Bluetooth 5 (LE) protocols. The board comes with an external antenna to enhance signal strength for wireless applications. It also features a small, sophisticated form factor combined with a single-sided surface mount design. It is equipped with rich interfaces, with 11 digital I/0s that can be used as PWM pins and 4 analog 1/0s that can be used as ADC pins. It supports four serial interfaces including UART, 12C and SPI. There's also a small reset button and a bootloader mode button on the board.
