Finger Print Sensor R307 -TTL UART

2,800.00 

Description

Finger Print Sensor R307 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 Finger Print Sensor R307 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.

Features

Note: We test the product before shipping.  We do not provide help related to programing. All details and protocol are given in download.
There is no warranty on the module. These can easily get damaged with wrong polarity or high voltage given to it. So be careful before power on. Internal LED does not come or stay on all the time, It only comes on when you give command to read fingerprint.
