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, we wouldn’t leave you a manual and a “good luck!” – we’ve written both anArduino libraryandCircuitPython libraryso that you can get running in under 10 minutes. The library can enroll and search so it’s perfect for any project.We’ve also written a detailed tutorial on wiring and use of these types fingerprint sensors.
