ESP32C3 PRO MINI is an IoT mini development board based on the ESP32-C3 WiFi/Bluetooth dual-mode chip. ESP32-C3 is a 32-bit RISC-V CPU that includes an FPU (floating point unit) that can perform 32-bit single- operations and has powerful computing power. It has excellent performance and supports IEEE 802.11 b/g WiFi and Bluetooth 5 (LE) protocols. The board comes with a ceramic antenna and an antenna mount to enhance the signal strength of wireless applications. It also has a small and exquisite appearance combined with a single-sided mount design. It is equipped with a rich interface, 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 such as UART, and SPI. There is also a small reset button and a bootloader mode button on the board. ESP32C3SuperMini is a high-performance, low-power, and cost-effective IoT mini development board, suitable for low-power IoT applications and wireless wearable applications.
