ESP32C3SuperMini is an IoT mini development board based on the Espressif ESP32-C3 WiFi/Bluetooth dual-mode chip. The ESP32-C3 features a 32-bit RISC-V CPU with FPU (Floating Point Unit), capable of performing 32-bit single-precision operations, delivering strong computing performance. It offers excellent RF performance and supports IEEE 802.11 b/g WiFi and Bluetooth 5 (LE) protocols. The board includes an external antenna to enhance signal strength for wireless applications. The compact and sophisticated design features a single-sided component layout, making it ideal for wearables and small-scale projects. It provides rich interface options, including 11 digital I/O pins that support PWM and 4 analog I/O pins that support ADC. It supports multiple serial interfaces: UART, I2C, and SPI. The board also includes a reset button and a bootloader mode button.
