Fingerprint Scanner Hookup Guide
This Tutorial is Retired!
Note: This tutorial is for the GT-511CXX models. If you are using any of the newer models (i.e. GT-521F32 and GT-521F52), please refer to the new Fingerprint Scanner (GT-521Fxx) Hookup Guide.

Raspberry Pi Example Code
There’s a Raspberry Pi Python Library for this fingerprint scanner if you look at the post by user jeanmachuca in the Pi forums => https://www.raspberrypi.org/forums/viewtopic.php?f=61&t=74178 .
There appears to be an article that uses the GT-511C1R with a Raspberry Pi as a server and SQLite [ FingerScanner: Embedding a Fingerprint Scanner in a Raspberry Pi ]. Based on this information, it’s possible to have remote management of a database on multiple fingerprint scanners from one server.
Node.js Example
There’s an example in Node.js with an API. I have not tested this feature before but try looking at this GitHub repository => https://github.com/the-AjK/GT-511C3 .
BeagleBone Black Example Code
There's a BeagleBone Black Python Library by user JamesMarcogliese's capstone design team located here => https://github.com/JamesMarcogliese/Fingerprint_Scanner-TTL .
