## Description

Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. It's easy to use and more affordable than ever!

These modules are typically used in safes - there's a high powered DSP chip that does the image rendering, calculation, feature-finding, and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash, and search. 

It comes with an 8-pin 1mm pitch connector with 0.1" header sockets for plug-and-play with a breadboard or dev kit. You can also easily cut off and solder directly to the wires. The cable is color-coded so it's easy to wire up:

- Red is 3.3V power
- Yellow is TTL Serial TX
- White is TTL Serial RX
- Black is Ground
 
But, of course, Adafruit wouldn't leave you a manual and a "good luck!" - Adafruit have written both an [**Arduino library**](https://github.com/adafruit/Adafruit-Fingerprint-Sensor-Library) and [**CircuitPython library**](https://github.com/adafruit/Adafruit_CircuitPython_Fingerprint) so that you can get running in under 10 minutes. The library can enroll and search so it's perfect for any project. [Adafruit have also written a detailed tutorial on wiring and use of these types fingerprint sensors](https://learn.adafruit.com/adafruit-optical-fingerprint-sensor).
