ESP32-C3 Mini Development Board is an IoT mini development board based on the ESP32-C3 Wi-Fi/Bluetooth dual-mode chip. The ESP32-C3 features a 32-bit RISC-V single-core processor with an FPU (floating-point unit) supporting 32-bit single-precision operations. It delivers strong computing performance, excellent RF performance, and supports IEEE 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE). The board includes a ceramic antenna and an IPEX antenna connector to enhance wireless signal performance. It features a compact, sleek design with a single-sided surface-mount layout. It offers rich peripheral interfaces: 11 digital I/O pins (supporting PWM), 4 analog I/O pins (supporting ADC), and multiple serial interfaces including UART, I2C, and SPI. A reset button and a bootloader mode button are also provided. This high-performance, low-power, and cost-effective mini development board is suitable for low-power IoT applications and wireless wearable devices.
