Finger Print Sensor Module – R307


In stock

R307 is a finger print sensor module with TTL UART interface. The user can store the finger print data in the module and can configure it in 1:1 or 1: N mode for identifying the person.The FP module can directly interface with 3v3  Microcontroller. A level converter (like MAX232) is required for interfacing with PC.
