I am working on using the F32 fingerprint scanner with a 5V arduino pro mini. As far as I can tell, I’ve hooked it up correctly using a logic level converter with the qwiic cable suggested with the product. I’m using FPS_blink to test it, and it’s not working. Nothing even happens. I’m using pins 4 and 5 for software serial like I’m supposed to as well. I even bought a second sensor because I thought it was faulty, but no dice. I even hooked it up to my 5V ftdi with the sdk software demo and nothing happened, though I know that is probably because I need the 3.3V ftdi for that. What could be going on here?
Hello tiggbigms25,
Sorry to hear that you’re having issues with the fingerprint scanner. Can you provide any schematics or pictures of your setup? You can even try to provide some code if you’ve modified the example code in any way.
