If you're using Windows 7 or 8.1, you'll need to install a driver to use a CircuitPython-compatible board. You do not need to install drivers on Mac, Linux or Windows 10.
First, uninstall any older versions of the driver with the following steps:
- Unplug any boards.
- Navigate to Uninstall or Change a Program by opening Control Panel->Programs->Uninstall a program.
- Uninstall everything named "Windows Driver Package - Adafruit Industries LLC ...".
Next, download the new 2.5.0.0 (or higher) Adafruit Windows Drivers Package using the following link:
When running the installer, you'll be shown a list of drivers to choose from. You can check and uncheck the boxes to choose which drivers to install.
It is recommended that you upgrade to Windows 10. Windows 10 makes the drivers unnecessary and solves other problems.There are currently no plans to update the available drivers, given that Windows 7 is end-of-life. As of this writing, you can still upgrade for free from Windows 7 or 8.1 to Windows 10. See these links.
