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

FMC PMO
Format: Kindle
I just felt like two things 1. The character development wasn’t there the character consistency wasn’t there, especially with the FMC. 2. The FMC would literally make the guys feel bad and keep bringing up that they don’t want her there, but then her whole thing has been. I don’t wanna be here so either you wanna be there or not but if you give off vibes that you don’t wanna be there people are not gonna want you there.

Hahahha omg I love Laurie. Momma don't care if you're an Uber alpha, she'll still middle name you & give you a dressing down hahaha. But really, this was a great read, great pacing for a fast paced book (timeline-wise) & great characters that actually felt individual. Plus I always love psycho puppy alphas haha.

Well, this was a really good read. I really enjoyed it. I liked the characters for the most part. Couldn’t quite connect with Darius. Still a very good read.
