For ESP32C3SuperMini is an IoT mini development board based on the Espressif for ESP32C3 WiFi/Bluetooth dual mode chip. For ESP32-C3 is a 32-bit RISC-V CPU that includes an FPU (floating point unit) and can perform 32-bit single precision operations with powerful computing power. It has excellent RF performance and supports IEEE 802.11 b/g/n WiFi and Bluetooth 5 (LE) protocols. This board comes with an external antenna to enhance the signal strength of wireless applications. It also has a compact and exquisite appearance combined with a single surface mount design. It is equipped with rich interfaces, with 11 digital I/Os that can be used as PWM pins and 4 analog I/Os that can be used as ADC pins. It supports four serial interfaces: UART, I2C, and SPI. There is also a small reset button and a boot loader mode button on the board. Based on the above characteristics, ESP32C3SuperMini is positioned as a high-performance, low-power, and cost-effective IoT mini development board, suitable for low-power IoT applications and wireless wearable applications.
