First off, if this is the wrong Stackexchange site, please let me know so I can ask on the correct site.

I'm contemplating installing Windows 10 IoT Core on my Raspberry Pi model 3B+ (so ARM platform) and using it to display a UWP app. Problem is, I need to connect a Fingerprint Scanner to it, which only has 6 pins for UART. Question now is, if I get a USB - UART converter, which drivers do I need to get to install them on my IoT Core?

You should be wiring in the UART directly from the fingerprint scanner to the Raspberry Pi. Do not try to convert to USB because then you have an unnecessary device driver problem. There are samples for reading from Serial UART on Windows 10 IoT core that work reasonably well.

  • Also I need to use a USB port, the GPIO pins are occupied by a POE Hat, and I know pass through pins exist but aside from not owning some, I've heard concerns that the GPIO pins could damage my fingerprint scanner
