Quick note to myself in future. To use Waveshare RP2040-zero in Arduino IDE you need to:

  1. https://thonny.org/ download app
  2. connect RP device
  3. press „boot” button
  4. install Micropython for RPi pico H
  5. reboot device (BOOT button)
  6. start Arduino IDE
  7. select „COMx” port + Raspberry Pi Pico as board
  8. upload ANY sketch with IMPORTANT action: while in Output there will be line of dots press BOOT and RESET button on RP device at SAME TIME.
  9. now you can upload ANY sketch into RP2040-zero from Arduino IDE without any issues.
