Adafruit Itsybitsy nRF52840

Either use the drag and drop UF2 method or more steps involved - Arduino uploading method. For the UF2 method

  • Download the UF2 file for the itsybitsy board in the current release

  • Double click that reset button. You will then get a USB drive on your computer. Drag and drop the UF2 file to the root of that drive.

  • It SHOULD disconnect from your pC if successful – but as I say the loghts should change colour to Green

  • More details see the steps herearrow-up-right

Or the Arduino uploading method.
