R307 Finger Print Sensor Module

An improved and compatible version of the R305 Finger Print Sensor Module at a great price.

R307 is an advanced version of the R305 finger print sensoring module having the same software protocol but with significant improvements. This sensor module allows you to store fingerprint data and configure it for accurate identification. It is a 3.3V compatible sensor module that can directly interface with a 3v3 or 5v microcontroller. A level converter, like MAX232, is necessary for interfacing with a PC.
