ESP32C3 PRO MINI development board onboard ESP32-C3FH4 chip module WiFi Bluetooth development board ESP32C3 PRO MINI development board onboard ESP32-C3FH4 chip module WiFi Bluetooth development board ESP32C3 PRO MINI is an IoT mini development board based on the Espressif 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 precision operations and has powerful computing capabilities. It has excellent RF performance and supports IEEE 802.11 b/g/n WiFi and Bluetooth 5 (LE) protocols. This board comes with a ceramic antenna and IPEX antenna mount, which can enhance the signal strength for wireless applications. It also has a compact and exquisite appearance combined with a single-sided surface mount design. It is equipped with rich interfaces, with 11 digital I/O available as PWM pins and 4 analog I/O available as ADC pins. It supports four serial interfaces: UART, I2C, and SPI. There is also a small reset button and a bootloader 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.
