Fingerprint 2 Click is a new fingerprint scanner Click board™ simplified for everyone's use and it's very easy to implement! This add-on board consists of a high-speed Nuvoton processor which carries high-performance fingerprint algorithm developed for on-board A-172-MRQ fingerprint sensor from company ByNew Technology Inc. This board can be used as a standalone device when connected over USB to PC or it can be controlled by the MCU/processor over serial UART interface. Board is already coming with preprogrammed firmware capable of storing up to 24 different fingerprints at the same time, as well as recognition algorithm for fingerprint comparison. This board enables you that in the easiest and fastest way integrate biometric security into your design.
Fingerprint 2 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.
This Click board™ features an A-172-MRQ, a 2D capacitive fingerprint sensor with active scanning area of 8.8 x 8x8 mm and resolution of 176 x 176 pixels. The sensor is based on capacitive-contact technology with hardened surface and enhanced ESD immunity. On board Nuvoton M2301 MCU which serves as interface IC and control unit on this board, interface this sensor over high speed SPI interface and comes with built-in fingerprint matching capability while leaving most of the chip resource to application developers. Developers can develop fingerprint-related products based on the communication protocol without the advanced knowledge of fingerprint identification.
The Fingerprint 2 Click has stable performance and simple structure. The simplified functions for faster and easy development include fingerprint comparison, image scanning transmission, search, registered fingerprint storage and system unique internal code protection mechanism. The fingerprint comparison program can register at most 24 fingerprints, the comparison speed is fast and the correct rate is very high.
Thanks to the Nuvoton MCU with the on-chip crypto-accelerator, Cortex-M23 TrustZone, and XOM facilities that is communicating with the fingerprint sensor and providing information to the host, Fingerprint 2 Click board™ can be interfaced with commands over UART protocol (baud rate 115200) or USB 2.0 full speed.
For proper operation Fingerprint 2 Click board™ needs to be supplied with 3.3V and 5V. However, note that this board it is designed to be operated only with 3.3V logic levels. Therefore a proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with logic levels of 5V.
BYNEW QUICKICK ULTILITY TOOL
For using and controlling Fingerprint 2 Click with PC Application from ByNew you will need first to connect your board to PC by using USB or some TTL converter for UART. After that you can start Utility tool BNQuickick.exe and select the COM port and Baud rate to operate/control this board.
Since this application is simplifying testing our board and acts as MCU host you can use the same commands from Fingerprint 2 Click example to control our board.
