Drivers (If You Need Them)

Windows Driver Installation

Windows 10

After plugging the board in, Windows will try to search the Internet for drivers. They should automatically install for Windows 10 without any issues.

Manual Installation

However, if you run into issues, you may need to install the drivers manually. Click the button below to download the drivers from the GitHub Repo.

Then follow the steps below to install the drivers:

  1. After downloading, extract the ZIP folder and copy down the location of the sparkfun.inf and files. This will be located in your downloads folder under .../Arduino_Boards/sparkfun/samd/drivers/.
  2. Open your Device Manager
    • In Windows 10, simply search for "Device Manager" and select the Windows app
    • (Start > Run > "devmgmt.msc", should work on almost any version of the OS.)
  3. In the Device Manager, expand the "Other devices" tree -- you should see an entry for "Unknown Device", Right-click and select Update Driver Software...

  4. Select Browse my computer for driver software. On the next screen
  5. Paste the directory location of your sparkfun.inf and files into the search location. Then hit "Next".
  6. Click "Install" when the next pop-up questions if you want to install the driver.
  7. The driver installation may take a moment, when it's done you should be greeted with a "successfully updated your driver software" message!

Windows 7

If you are using a Windows 7 OS, you will need to install the SAMD drivers using the SAMD Windows 7 Installer. Head over to the GitHub repo to install the executable.

Scroll down the page to the assets in the Latest release and click on the '.exe to download. The version number may be different depending on the release. The image below shows sparkfun_drivers_1.0.5.3.exe .
