Capacitive Fingerprint Scanner with ESP32
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
I need help to interface the fingerprint scanner with the ESP32. When I tried to do it and run an example from “DFRobot_ID809.h” library (fingerprint registration) , it showed “communication with device failed, please check connection”.

Ensure proper wiring and connections. Double-check baud rates and power supply.

Share the circuit diagram or connection chart. Also, check if your jumper wires are all OK.

Could you please share us with a photo of your wire connection? That will help us to check if you had missed something.
