- Hold down the
boot
button whilst plugging in the USB cable into your computer’s USB port at the same time. You may see it pop up as a new device on your computer but just ignore that for now. - Thonny or Mu
- Download the RPI_PICO-2024022-v1.22.2.utf2
- Drag and drop on it.
- Launch Mu and see if it is connected.
