The Tufty2040 comes with the UF2 bootloader already installed.

Flash your TinyGo program to the board using this command:
```
tinygo flash -target=tufty2040 [PATH TO YOUR PROGRAM]
```
The Tufty2040 board should restart and then begin running your program.

Any troubleshooting tips go here.

You can use the USB port to the Tufty2040 as a serial port.

TinyGo has support for the RP2040’s on-board Programmable Input/Output (PIO) block.
