Description
R305 fingerprint module has RS232 and USB1.1 at the same time, dual interface to communicate with the outside; USB1.1 interface can be connected to the computer; RS232 interface is TTL level, the default baud rate is 57600, can be changed, please refer to the communication protocol
To connect with single-chip microcomputers, such as ARM, DSP and other devices with serial ports, 3.3V 5V single-chip microcomputers can be directly connected. Connecting to a computer requires level conversion, please pay attention to level conversion, such as MAX232 circuit.
After the fingerprint module is powered on, the fingerprint collection window will flash once, indicating that the self-check is normal. If it does not flash, please carefully check the power supply to see if it is connected reversely or incorrectly. The chip has some heat during normal operation. This is a normal phenomenon. It has been strictly tested and can be used with confidence.
