Description: Fingerprint scanners are awesome. Why use a key when you have one right at the tip of your finger? Unfortunately, they’re usually unreliable or difficult to implement. Well not anymore! We’ve found this great fingerprint module from ADH-Tech that 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 on-board optical sensor and 32-bit CPU. All you need to do is send it simple commands. 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. As well as the fingerprint “template,” the analyzed version of the print, you can also retrieve the image of a fingerprint and even pull raw images from the optical sensor!

This is the more economical version of the GT-511 which has a decreased memory capacity (compared to the GT-511C3). The module can only store up to 20 different fingerprints but is capable of 360° fingerprint recognition and download and upload templates using serial interface. If you are on a budget and need only a small number of fingerprints stored, this is the perfect option for you!

The module is small and easy to mount using two mounting tabs on the side of the sensor. The on-board JST-SH connector has four signals: Vcc, GND, Tx, Rx. A compatible JST-SH pigtail can be found in the related items below. Demo software for PC is available in the documents below, simply connect the module to your computer using an FTDI Breakout and start the software to read fingerprints!

Note: The module does not come with a cable, check in the Recommended Products section for an appropriate one.

Dimensions: 37 x 17 x 9.5 mm

So comfortable!
These work great and very comfortable. I put these on with heel moisturizer cream at bed time. Heels were improved overnight. They are washable too!

Just aren’t large enough.
This is a great idea, and I can wear socks over them and not notice they are there. I just wish they came in a larger size. When I put cream around the edges of my heels where the cracks always are, I cannot stretch the socks wide enough to clear the heel without smearing the cream onto my fingers or on the sock cuff. They do stay in place and aren't squishy at all when walking. They smell good too. The price is right. I wore them overnight and my heels were indeed much softer and smoother than before, and felt moist (tacky) where the cream had been. So they do an amazing job, but after using them six nights, they just aren’t large enough for me to put on without a hassle.

yoga socks
I’m a weirdo and don’t like to walk around barefoot. So, these help me feel like I’ve got socks on while allowing my toes to breathe. I just wear them around the house. They can work as flipflop socks for a quick trip to the mailbox. I do like to randomly hit the occasional yoga pose so the grippiness is helpful in that regard. I have wide feet and have not found the toe openings to be tight or any other fit problems. So far they have survived standard machine washing.Unfortunately, when I first tried on a pair, the material started to rip. I wear a 7-7.5 shoe size. I think these are made for smaller feet. The material is thin and doesn't stretch. The colors are pretty and it's a good price. I have to return them due to being too small. If you have smaller feet, they are worth trying.

My Favorite Style of Yoga Socks — I Love These
There are so many types of yoga socks out there, but this style is my absolute favorite. These toeless yoga socks are perfect: no individual toe slots, crew‑length coverage, and solid grippies on the bottom. I love them so much. They stay put, they feel great, and they give me the barefoot freedom I want without slipping around on the mat. Total win.
