Interface Description of Fingerprint Sensor:

The R307 fingerprint module has two interfaces. One is TTL UART and the Second is USB2.0, USB2. These two interfaces can be connected to the computer. RS232 interface is a TTL level.  And its default baud rate is 57600. But it can be changed. It can be referred to as a communication protocol. It can refer to microcontroller also such as ARM, DSP, and other serial devices with a connection. 3.3V and 5V can be connected directly. It needs to connect the computer level conversion note, embodiments such as the MAX232 circuit.
