Before you plug in your board, you'll need to possibly install a driver!

Click below to download our Driver Installer

Download and run the installer

Run the installer! Since we bundle the SiLabs and FTDI drivers as well, you'll need to click through the license

Select which drivers you want to install:

By default, we install the Feather 32u4 , Feather M0, Flora and Trinket / Pro Trinket / Gemma / USBtinyISP drivers.

You can also, optionally, install the Arduino Gemma (different than the Adafruit Gemma!), Huzzah and Metro drivers

Click Install to do the installin'

Next, plug in the device into an open USB slot. You should get this popup:

Driver installed! Now go to your Device manager (Start Menu -> Settings -> Control Panel -> System -> Hardware) and look for the device:

Mac OS X & Linux

A driver is not required.
