## Description

desertcart.com: flashtree FPM11A Green Light Optical Fingerprint Reader Sensor Module 6 Pins for Arduino Mega2560 UNO R3 : Electronics

Review: Works Great, Touch sensor is nice! - Fingerprint Scanner works great. But - awesome bonus is - you can wire Blue (Touch VCC) and Yellow (Touch Signal High) - and then wrap your call to getFingerprintID(); inside a digitalRead(SENSOR_PIN) == HIGH. Of course, in setup(), you also need pinMode(SENSOR_PIN, INPUT); (and at the top of your program, define what pin will be you SENSOR_PIN... for me, I used 4 - since that would be right next to other pins being used: 2 & 3). const int SENSOR_PIN = 4; This way - your device is only scanning for prints when you touch it... and the LEDs stay off when you are not touching it.
Review: Useful, Efficient Fingerprint Sensor! - This was the third fingerprint sensor we bought for a project, and it worked like a marvel. The 6-pin wire plugged easily into our breadboard and Arduino Uno R3, no soldering required. The fingerprint sensor itself was very efficient, and worked well with our project ( a fingerprint-based Arduino attendance system). Note that only four out of the six pins need to be used for most projects - wires red, green, white and black (no blue/yellow). Five Stars!

## Features

## Questions & Answers

**Q: can you connect this sensor to the raspberry pi 3 B Plus? and if so, what is the pinout? I've tried any possible combined and it does not work!**
A: Raspberry PI 3  Plus has bluetooth, The uart is connected to the bluetooth by default, so you can't use it unless set to turn off bluetooth. Another easier way is to use USB TO TTL module, such as FT232RL OR CP2102 breakout connect to the USB port

**Q: Does the light stay on all the time or just wen a finger is applied?**
A: it is not all the time,just went need get a finger press.

**Q: Mine doesn't light up and the enroll code in Adafruit Library doesn't detect it. Is that a corregible mistake or is it just damaged?**
A: 1, first open the ARDUINO IDE software, input fingerprint in the Library management, installation adafruit fingerprint Sensor Library Ver 1.1.3
2, open  file --> example --> adafruit Fingerprint Sensor Library --> enroll, to download the program to the arduino uno r3,
3, open the serial port monitor, baud rate is set to 9600, we first not connect the fingerprint module, a serial port monitor displays

The Adafruit Fingerprint sensor enrollment
Did not find fingerprint sensor: (


4, connect the fingerprint module to the board, 
RED < - > 5 v,
BLACK < - > GND, 
GREEN < - > 2, 
WHITE < - > 3, 
the yellow and blue do not need the connect. 

Then reopen the serial port monitor, It will show:

The Adafruit Fingerprint sensor enrollment
Found fingerprint sensor.
Ready to enroll a fingerprint!
Both Please type in the ID # (from 1 to 127) you want to save this finger as...

You can send 1 to 127 text that enroll fingerpirnt. and then the fingerpint module will be light up.

**Q: Is this conpatible with raspberry pi 3?**
A: Yes, but it's not easy

### ⭐ Not working on Raspberry pi. tested 3, 3b+ or 5
*by A***L on July 29, 2025*

Worse luck ever, I order tow of this and none of them work. BLUE and RED to 5v and Black to Ground, Green RX (GPIO15), White TX (GPIO14).. Teste on Rapsberry pi 3, 3b+, 5 no luck.
