Grove Capacitive Fingerprint Scanner

Description

A module with a capacitive fingerprint sensor, which has a rectangular field and takes a fingerprint image with a resolution of 160 x 160 pixels (508 dpi). The module is based on the GD32 processor and a secure fingerprint collection algorithm. The sensor uses a self-learning feature that adds it to the database after each successful fingerprint recognition. An additional visual effect is that the correct detection of the imprint is signaled by RGB backlight. The board is equipped with a Grove connector, so it can be used with the Base Shield V2 and Arduino extension. The module communicates via the UART interface and is supplied with the voltage of 3.3 V or 5 V. Full documentation with examples of use is available on the product page.
