Xiao ESP32-C3 IoT Development Board

Seeed Studio XIAO ESP32C3 is an IoT mini development board based on the Espressif ESP32-C3 WiFi/Bluetooth dual-mode chip in a very tiny form factor. The ESP32-C3 chip is built around 32-bit RISC-V architecture with four stage pipeline and a Floating-Point Unit (FPU) for precision arithmetic operations. The chip also has 2.4GHz WiFi and Bluetooth 5(LE) support.
