:o
I bought a bargain basement fingerprint reader, that also enables the image to be scanned too.
It comes with a Windows "SFG Demo" - that uses the COM port serial pins of the reader.
This needs an entire Arduino or ESP32 to pass through the serial data to the USB connection of the PC.
But there appears to be a USB connector on some of these boards AND mine is like this - there's THREE extra pins!
Ground, TX, RX, Ground, Sensor touched, 3.3V, D+, D-
The D- / D+ lines are the USB connection - but I have no idea where to find the drivers for it.
I've googled AS608 fingerprint reader drivers - but nothing comes up for anywhere!
Has anyone ever got a direct USB connection between the scanner and a USB cable?
