Brief description of R307 fingerprint module:

1. Fingerprint capacity:

The storage capacity of R307 fingerprint module is 1000. 

 

2. Description of interface:

R307 fingerprint module has RS232 and USB2.0 at the same time.USB2.0 interface can connect to the computer;RS232 interface is TTL level, and the default baud rate is 57600, which can be changed. Please refer to the communication protocol.It can be connected with microcontroller, such as ARM, DSP and other equipment with serial port, and the microcontroller of 3.3v and 5V can be connected directly.When connecting to the computer, please pay attention to the level conversion, such as the MAX232 circuit. 

 

3. Module detection

After the fingerprint module is powered on, the fingerprint collection window will flash, indicating that the self-test is normal. If it does not flash, please carefully check the power supply, whether it is connected backwards or wrongly.The chip has some heat when working normally, this is normal phenomenon, the product has passed strict test, can rest assured to use.
