UART Fingerprint Sensor (R)

Description

Integrated capacitive fingerprint sensor communicating with the external system via the UART interface. The module has a rectangular sensor field and downloads a fingerprint image with a resolution of 508 dpi.

The module is based on a Cortex processor and a secure algorithm for taking fingerprints. The fingerprint sensor offers functions such as fingerprint registration, image acquisition, function search and fingerprint matching. Thanks to the simple communication based on the UART interface, the sensor is simple to use and can be easily integrated with fingerprint checking applications that require small size and high precision.
