# Title: Fingerprint 2 Click Board™ ## Description: How Does The Fingerprint 2 Click Board™ Work? The Fingerprint 2 Click Board™ features an A-172-MRQ, a 2D capacitive fingerprint sensor with an active scanning area of 8.8 x 8x8 mm and a resolution of 176 x 176 pixels. The sensor is based on capacitive-contact technology with a hardened surface and enhanced ESD immunity. Onboard Nuvoton M2301 MCU which serves as interface IC and control unit on this board, interface this sensor over a 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 Board™ has stable performance and a 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 the 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 UTILITY TOOL For using and controlling the Fingerprint 2 Click Board™ 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 the 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 the Fingerprint 2 Click Board™ example to control our board.

Additional Notes and Information

Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.

MIKROSDK

The Fingerprint 2 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
