Blink

Now you can upload your first blink sketch!

Plug in the Gemma M0, Trinket M0, Metro M0 or Feather M0 and wait for it to be recognized

by the OS (just takes a few seconds). It will create a serial/COM port, you can now select it

from the dropdown, it'll even be 'indicated' as Trinket/Gemma/Metro/Feather M0!
