Fingerprint click™ is a click board solution for adding biometric security to your design. It carries theGTS-511E2 module, which is the thinnest optical touch fingerprint sensor in the world. The module comprises a CMOS image sensor with a special lens and covering that records real fingerprints while resiting 2D fakes. The click™ board also carries an STM32 MCU for processing the images and forwarding them to an external MCU or PC. We created a Windows application that provides an easy interface for communicating with Fingerprint click™. The board is designed to se a 3.3V power supply.
