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 22.214.171.124 (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.
