The R307 is a fingerprint sensor module with a TTL UART interface. Users can store their fingerprint data in a module and configure it in 1: 1 or 1: N mode to identify an individual. The FP module can be connected directly to the 3v3
microcontroller.
A level converter (such as MAX232) is required to connect to a PC. The
R307 Fingerprint Module has two interfaces, TTL UART and USB 2.0, which allow you to connect the USB 2.0 interface to your computer. The RS232 interface is TTL level and the default baud rate is 57600, which can be changed. See Communication Protocol. You can also connect directly to microcontrollers such as ARM, DSP and other connected serial devices, as well as 3.3V 5V microcontrollers. It is necessary to connect embodiments such as computer level conversion, cautions regarding level conversion, and MAX232 circuit.
