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.

The R307 fingerprint module has two interface TTL UART and USB2.0, USB2.0 interface can be connected to the computer; RS232 interface is a TTL level, the default baud rate is 57600 , can be changed, refer to a communication protocol ; can And microcontroller, such as ARM, DSP and other serial devices with a connection, 3.3V 5V microcontroller can be connected directly. Needs to connect the computer level conversion, level conversion note , embodiments such as a MAX232 circuit. 
Pinouts :-
Pin#    Pin Name        Details
1    5V                Regulated 5V DC
2    GND                Common Ground
3    TXD                Data output - Connect to MCU RX
4    RXD                Data Input - Connect to MCU TX
5    TOUCH        Active Low output when there is touch on sensor by finger
6    3.3V                Use this wire to give 3.3V to sensor instead of 5V
USB Cable Connections are 5V/D+/D-/GND (Optional)
