Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. It's easy to use and more affordable than ever!

These modules are typically used in safes - there's a high powered DSP chip that does the image rendering, calculation, feature-finding, and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash, and search.

It comes with an 8-pin 1mm pitch connector with 0.1" header sockets for plug-and-play with a breadboard or dev kit. You can also easily cut off and solder directly to the wires. The cable is color-coded so it's easy to wire up:

3.3V power
TTL Serial TX
TTL Serial RX

Hardware connection:
Module via a serial communication interface, directly with 3.3V or 5V power microcontroller communication: Module data transmission feet (2
Foot TD) connected to the data bit machine receiving end (RXD), data receiver module feet (3 feet RD) connected to the data sender bit machine (TXD).
For the RS-232 level (for example: PC machine) for PC communication, increase the level conversion between the module and the host computer
