Seeed Studio XIAO ESP32C3
The Seeed Studio XIAO ESP32C3 is a tiny development board based on the Espressif ESP32C3 32-bit RISC-V CPU microcontroller with 400KB of SRAM and 4MB of onboard flash storage. Thanks to the onboard radio, it supports both WiFi and Bluetooth wireless communication.

Flashing
CLI Flashing
-
Flash your TinyGo program to the board using this command:
tinygo flash -target=xiao-esp32c3 [PATH TO YOUR PROGRAM] -
The XIAO ESP32C3 board should restart and then begin running your program.
Troubleshooting

Notes
No onboard LED
The XIAO-ESP32C3 does not have an onboard LED, so the normal examples/blinky1 program cannot be used on this board.
WiFi
You can use the onboard wireless chip for WiFi using the espradio package.
