Previously, we encountered many detours while using AS608. This time, I hope that as beginners, we can learn from our experiences and introduce AS608.

Using Microcontroller + AS608 with Program Heat: 22

Usage of Fingerprint Module AS608: 1 red wire: Vcc, connect to 3.3V power supply, do not connect to power supply above 3.3V Yellow wire: Connect to the TX end of the microcontroller's serial port 3 white wires: Connect to the RX end of the microcontroller's serial port 4-pin black wire: GND, GND for the 3.3V power supply 5th blue wire: Module touch sensing signal output (high level indicates touch detected), needs to be connected to VTI to 3.3V Green wire: Power for the module's touch sensing circuit, can be connected in parallel with the red wire. In this program, pins 5 and 6 can be left unconnected. Pins 2 and 3 should first be connected to the TX and RX of the microcontroller respectively to ensure normal communication. This program is designed based on the 8051 microcontroller and can display information on an LCD1602. It includes functions such as fingerprint enrollment and fingerprint detection.
