![]() That being said, all of our Qwiic cables, like our 100mm version, will work for this board. Note: Please be aware that even though this fingerprint scanner is equipped with the same connector we use on all of our Qwiic boards, it is NOT Qwiic or I 2C compatible. A compatible JST-SH pigtail can be found in the Hookup Accessories section below. The onboard JST-SH connector has four signals: Vcc, GND, Tx and Rx. The module is small and easy to mount using four mounting holes surrounding the sensor. Additionally, the GT-521Fxx series features a resolution of 450dpi, 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! It is capable of 360° fingerprint recognition and download/upload templates using serial interface. A Fingerprint scanner is a system that scan and analyze the fingerprint of the user and verifies the persons identity. This module is the economical version of the GT-521F52 and can store up to 200 different fingerprints. In addition to the fingerprint "template," the analyzed version of the print, you can retrieve the image of a fingerprint and even pull raw images from the optical sensor! The fingerprint scanner can store different fingerprints, and the database of prints can even be downloaded from the unit and distributed to other modules. ![]() To get started, just register each fingerprint that you want to store by sending the corresponding command and pressing your finger against the reader three times. The module itself does all of the heavy lifting behind reading and identifying the fingerprints with an onboard optical sensor and 32-bit ARM Cortex M3 processor. Well not anymore! This great GT-521F32 fingerprint module from ADH-Tech communicates over TTL Serial so you can easily embed it into your next project. Fingerprint scanners are awesome! Why use a key when you have one right at the tip of your finger? Unfortunately, they're often unreliable or difficult to implement.
