When matching, user enters the finger through optical sensor and system will generate a template of the finger and compare it with templates of the finger library. The system will process the two-time finger images, generate a template of the finger based on processing results and store the template. When enrolling, user needs to enter the finger two times. The R307 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 can And microcontroller, such as ARM, DSP and other serial devices with a connection, 3.3V and 5V microcontroller can be connected directly.įingerprint processing includes two parts: fingerprint enrollment and fingerprint matching (the matching can be 1:1 or 1:N). Communication baud rate (UART): (9600xN) bps, default: 57600bps.Matching method: Comparison method (1: 1). Fingerprint image input time: Supply current: Working current: 50mA (typical) Peak current: 80mA.A logic level converter (like MAX232) is required for interfacing with PC. The FP module can directly interface with 3v and 5v Microcontroller. The user can store the finger print data in the module and can configure it in 1:1 or 1: N mode for identifying the person. R307 is a finger print sensor module with TTL UART interface.
