Rugged Panel Mount Fingerprint Sensor with Bi-Color LED Ring - R503

Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. It even has an LED ring built around the detection pad, which can be set to red, blue or purple (as well as some fading/blinking effects) for a great user experience.

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. You can also enroll new fingers directly - up to 200 fingerprints can be stored in the onboard FLASH memory.

We like this particular sensor because its a nice rugged metal body, with panel-mounting that will make it easy to add to any product or project. It also comes with a 6-pin Molex-style 1mm pitch connector, which you can easily cut off and solder directly to the wires.

But, of course, we wouldn't leave you a manual and a "good luck!" - we've written both an Arduino library and CircuitPython library so 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.
