R307 Fingerprint Module consists of an 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 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 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.
- Independent fingerprint collection, fingerprint registration, fingerprint comparison (1: 1), and fingerprint search (1: N) function.
- Low power consumption of the product
- A strong anti-static ability, the anti-static index reached 15KV above.
- Professional optical technology, precise module manufacturing techniques
- Suitable for different applications, security levels can be set by the user to adjust.
