| To build your TinyGo program without flashing it to the board, you can use the following command: | ||
|
|
||
| ```shell | ||
| tinygo build -o blinky.elf -size=short -gc=leaking --panic=trap -target=xiao-esp32c3 [PATH TO YOUR PROGRAM] |

| tinygo build -o blinky.elf -target=xiao-esp32c3 [PATH TO YOUR PROGRAM] |
I don't think these extra flags should be given, unless you specifically want those?
| To compile and flash your program to the board in one step, use: | ||
|
|
||
| ```shell | ||
| tinygo flash -port /dev/ttyUSB0 -target=xiao-esp32c3 [PATH TO YOUR PROGRAM] |

Why is this command repeated? A similar command is already listed above.
|
|
||
| - The XIAO ESP32C3 supports both WiFi and Bluetooth functionality. However, TinyGo's support for Bluetooth on this board may be limited or in development. | ||
| - The USB port on the XIAO ESP32C3 can be used as a serial port for debugging and communication. | ||
| - When using WiFi functionality, be mindful of power consumption as it can significantly affect battery life in portable projects. |

A line like this seems to imply we support WiFi on this device, which we do not. I would suggest removing it, to avoid confusion.

Normally it's not needed to configure the UART at startup, you can just use fmt.Println. Is this different for this board?

Why is the extra -port parameter needed? TinyGo should detect it automatically.
