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. Well not anymore! This great GT-521F52 fingerprint module from ADH-Tech communicates over TTL Serial so you can easily embed it into your next project. 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.

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 fingerprint scanner can store different fingerprints, and the database of prints can even be downloaded from the unit and distributed to other modules. 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!

This module is the upgraded version of the GT-521F32 and can store up to an astounding 3,000 different fingerprints! It is capable of 360° fingerprint recognition and download/upload templates using serial interface. 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!

The module is small and easy to mount using four mounting holes surrounding the sensor. The onboard JST-SH connector has four signals: Vcc, GND, Tx and Rx. A compatible JST-SH pigtail can be found in the Hookup Accessories section below.

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 I2C compatible. That being said, all of our Qwiic cables, like our 100mm version, will work for this board.

Saved my skin during an eczema flare up
This saved my skin! I had an eczema flare on my face, and my usual products weren’t working. A friend recommended the Avene brand and within 3 days of using this rescue barrier serum, my flare was almost completely gone! This saved my face!

PLEASE REVIEW — FORMULA CHANGED!!!
I wish I would’ve posted a review PRIOR to the formula changing but just know that I LOVED this serum. I’ve struggled with hormonal acne (PCOS) and eczema for as long as I can remember. Finally, last summer my dermatologist put me on (3) different RX including Spironolactone and Accutane. I was so tired so I stopped everything except for CeraVe cleanser, retinol (Tretinoin) and CeraVe healing ointment. My made up skin routine was working until I used too much Tretinoin and burned my face. I had read great reviews about this product so I thought, I might as well try it — and IT WORKED! I’ve been using this product for almost a year and I loved it. However, 3 weeks ago when I ordered it, I noticed the bottle had a green tint. I could tell after one use that the feel of the serum was different, more watery, not as thick as it used to be. The smell was also different. Still, I kept using it for nearly 2 weeks and I experienced 2 breakouts! Sure enough, I stopped the product and within a few days, my skin was back to normal. I am very upset because as someone who has extremely sensitive skin, this worked but unfortunately, the new formula isn’t for me.
