Description:-
The R307S (1000 Prints) Fingerprint Module includes an optical fingerprint sensor, a high-speed DSP processor, a high-performance algorithm for fingerprint alignment, high-capacity FLASH chips, and other hardware and software components.
It has a simple structure, stable performance, and features functions for fingerprint entry, image processing, fingerprint matching, searching, and template storage, among others.
A fingerprint sensor module called R307 has a TTL UART interface.
The FP module can directly interface with a 3v3 Microcontroller.
The user can configure the module in 1:1 or 1: N mode and store the fingerprint data there.
A level converter (like MAX232) is needed for the PC interface.
The RS232 interface is a TTL level, the default baud rate is 57600, can be changed, refer to a communication protocol, and can microcontroller, such as ARM, DSP and other serial devices with a connection, 3.3V 5V microcontroller can be connected to directly.
The R307 fingerprint module has two interfaces: TTL UART and USB 2.0. USB 2.0 interface can be connected to the computer. Requires connecting the computer for level conversion.
