Product Description
R305 Fingerprint Reader Module
R305 fingerprint module by the optical fingerprint sensor, high-speed DSP processors, high performance fingerprint matching algorithm, large capacity FLASH chip and other hardware and software configuration, stable performance, simple structure, with a fingerprint input, image processing, fingerprint matching, search and template storage other functions
Features:
*Functional: independently fingerprint, fingerprint registration, fingerprint matching (1: 1) and fingerprint search (1: N) function.
*Compact: product is compact, there is no external algorithm DSP chip circuit board has been integrated one, easy to install, less failure.
* Low power consumption: product overall power consumption is very low, for low-power requirements of the occasion.
* antistatic ability: antistatic ability has a strong, anti-static indicators have reached more than 15KV.
* simple application development: Developers can control instructions provided in accordance with their own fingerprint applicationdevelopment products, without possess professional knowledge of fingerprint identification.
* security level adjustable: suitable for different applications, the security level set by the user to adjust.
A brief description of R305 fingerprint module:
1. Fingerprint Capacity:
R305 fingerprint module storage capacity is 980.
2. Interface description:
At the same time there are fingerprints on the R305 module RS232 and USB1.1, dual interface to communicate with the outside world; USB1.1 interface can be connected to the computer; RS232 interface is a TTL level, the default baud rate is 57600, can be changed, refer tothe communication protocol; can and microcontrollers, such as ARM, DSP and other devices with a serial port connection, 3.3V 5Vmicrocontroller can be connected directly. Connected to the computer needs to be level conversion, please note the level conversion circuitsuch as MAX232.
3. Detection on module
After fingerprint module power, fingerprint capture window will flash, indicating that the self-test is normal, if not flash, please check the power is reversed, then the wrong and so on. When the chips have to work some hot,, this is a normal phenomenon, it has been rigorously tested, you can be assured.
