Description

GT-521F52 Fingerprint Scanner. This awesome GT-521F52 fingerprint module from ADH-Tech communicates via TTL serial, so you can easily use it in your next project. The module itself does all the heavy lifting behind reading and identifying fingerprints with a built-in optical sensor and a 32-bit ARM Cortex M3 processor.

Manual

To get started, simply register each fingerprint you want to save by sending the corresponding command and pressing your finger against the reader three times. The fingerprint scanner can store multiple fingerprints, and the database of prints can even be downloaded from the device and distributed to other modules. In addition to the fingerprint template, which is the analyzed version of the print, you can get the image of a fingerprint, and even extract raw images from the optical sensor!

This module is the upgraded version of GT-521F32, it can store up to 3000 different fingerprints! It is capable of 360° fingerprint recognition and download/upload templates by using serial interface. What's more, GT-521Fxx series adopts 450dpi resolution, with a false acceptance rate of <0,001% and a false rejection rate of <0,1% while only needing <1,5 seconds to identify a unique fingerprint!

The module is small and easy to mount using four mounting holes around the sensor. The onboard JST-SH connector has four signals: Vcc, GND, Tx and Rx.
