A brief description of R305 fingerprint module:
1. Fingerprint Capacity:
R305 fingerprint module storage capacity is 980 .
2. Interface description:
The R305 fingerprint module is also available in RS232 and USB1.1 , dual interface to communicate with the outside world ; USB1.1 interface can be connected to the computer; RS232 interface is a TTL level, the default baud rate of 57600 , can be changed, refer to the communication protocol ; can with the microcontroller, such as ARM, DSP and other devices with a serial port connection, 3.3V 5V microcontroller can be connected directly. Connected to the computer needs to be level conversion, please note the level conversion , cases such as the MAX232 circuit.
3. Detection on module:
Fingerprint module after power-up, the fingerprint capture window will flash, indicating that the self-test is normal, if not flash, please check the power is reversed, then the wrong and so on. Normal working hours are some hot chips ,, this is a normal phenomenon, it has been rigorously tested , you can be assured use .
