Split: Fingerprint sensor: 56 ╳ 20 ╳ 21.5mm
-One: 56 ╳ 20 ╳ 21.5mm
 
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
Circuitry (e.g.: MAX232 circuit)

Have you got any details of what the 6 connections are ?

The spec indicates that it has a TTL level Serial interface which sounds perfect for interfacing with the Arduino
