1.1. Supported operating systems

The Pololu Isolated USB-to-I²C Adapter works on Microsoft Windows 11, Windows 10, Linux, and macOS without any driver installation. The Windows driver we provide in Section 3 should allow the adapter to work on older versions of Windows, but we have not tested that. Driver installation is not required on Windows 10 and later, but installing the driver is recommended because it allows you to see the correct product name in the Device Manager instead of “USB Serial Device”.
