Even though in theory you don't need to - I recommend rebooting the IDE

Quit and reopen the Arduino IDE to ensure that all of the boards are properly installed. You

should now be able to select and upload to the new boards listed in the Tools->Board menu.

Feather M0 (for use with any Feather M0 other than the Express)

Feather M0 Express

Metro M0 Express

Circuit Playground Express

Gemma M0

Trinket M0

Install Drivers (Windows 7 Only)
