Description

Share this product

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)
