Description:
The Seeed Studio XIAO ESP32-C3 is an IoT mini development board based on the Espressif ESP32-C3 WiFi / Bluetooth dual-mode chip, featuring a 32-bit RISC-V CPU that delivers powerful computing performance with its efficient architecture. It has excellent radio frequency performance, supporting IEEE 802.11 b/g/n WiFi and Bluetooth 5 (BLE) protocols. This board comes with an external antenna included to increase signal strength for your wireless applications. It also has a small and exquisite form-factor combined with a single-sided surface-mountable design. It is equipped with rich interfaces and has 11 digital I/O that can be used as PWM pins and 4 analog I/O that can be used as ADC pins. It supports four serial interfaces such as UART, I2C, and SPI. There is also a small reset button and a bootloader mode button on the board. XIAO ESP32C3 is fully compatible with the Grove Shield for Seeeduino XIAO and Seeeduino XIAO Expansion board. It is a high-performance, low-power, cost-effective IoT mini development board, suitable for low-power IoT applications and wireless wearable applications.
