The R307S Optical Fingerprint Sensor Module is a fingerprint sensor module with TTL UART interface. The user can store the fingerprint data in the module and can configure it in 1:1 or 1:N mode for identifying the person. The fingerprint module can directly interface with 3.3V Microcontroller. A level converter (like MAX232) is required for interfacing with PC. The R307S Optical Fingerprint Sensor Module is an updated Improved Compatible version for the R305 Fingerprint Sensor Module
The R307S Fingerprint Module consists of optical fingerprint sensor, high-speed DSP processor, high-performance fingerprint alignment algorithm, high-capacity FLASH chips and other hardware and software composition, stable performance, simple structure, with fingerprint entry, image processing, fingerprint matching, search and template storage and other functions.
The R307S fingerprint module has two interface TTL UART and USB2.0. USB2.0 interface can be connected to the computer; RS232 interface is a TTL level, the default baud rate is 57600, can be changed, refer to a communication protocol and microcontrollers, such as ARM, DSP and other serial devices with a connection, 3.3V 5V microcontroller can be connected directly. Needs to connect the computer level conversion, level conversion note, embodiments such as a MAX232 circuit.
