Mac and Linux do not require drivers, only Windows folks need to do this step

Windows 10 users probably can skip this step, because Windows 10 already has many drivers built in. Try skipping the installation first to see if it's unnecessary.

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

Download Latest Adafruit Windows 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, we suggest selecting all of them so you don't have to do this again!

As of version 2.5.0.0, the Adafruit drivers package is no longer signed, and some of the drivers it contains are also no longer signed. You'll need to click the second item in this dialog box when it appears:

On Windows 7, by default, we install a single driver for most of Adafruit's boards, including the Feather 32u4, the Feather M0, Feather M0, Express, Circuit Playground, Circuit Playground Express, Gemma M0, Trinket M0, Metro M0 Express. On Windows 10 and 11 that driver is not necessary (it's built in to Windows) and it will not be listed.

The Trinket / Pro Trinket / Gemma / USBtinyISP drivers are also installed by default.

You can also, optionally, install the Arduino Gemma (different than the Adafruit Gemma!), Huzzah and Metro 328 drivers.

Click Install to do the installin'.

Note that on Windows 10 and Windows 11, support for many boards is built in. If you end up not checking any boxes, you don't need to run the installer at all!
