Capacitive Fingerprint Reader - fingerprint reader with UART/USB interface

Description

Integrated capacitive fingerprint sensor communicating with the external system via UART or USB interface. It has a rectangular-shaped sensor field and takes a fingerprint image with a resolution of 208x208 pixels. The module is based on the STM32F105 microcontroller and a safe algorithm for taking prints. The sensor offers functions such as fingerprint registration, image acquisition, feature search and fingerprint matching. Thanks to communication based on the UART and USB interface, the sensor is easy to use and can be easily integrated with fingerprint checking applications that require small size and high precision. Full documentation with examples is available on the product wiki page.
