Capacitive fingerprint sensor round with UART

This is a highly integrated, round, capacitive, all-in-one fingerprint sensor module. The module is controlled via UART commands and is easy to use. Its advantages include 360° omnidirectional verification, fast verification, high stability, and low power consumption. Based on a powerful Cortex processor, combined with a highly secure commercial fingerprint algorithm, the UART Fingerprint Sensor offers functions such as fingerprint capture, image capture, feature finding, template generation and storage, fingerprint matching, etc. Without knowledge of the complicated fingerprint algorithm, you only need to send a few UART commands to integrate a new fingerprint.

Fingerprint Sensor Features:

Commercial fingerprint algorithm, stable performance, fast verification, supports fingerprint capture, fingerprint matching, capturing fingerprint images,
Capacitive sensitive detection, just lightly touching the sensor surface for a quick check.
Highly integrated hardware, processor and sensor in a small chip, suitable for small applications.
Narrow stainless steel edge, large touching area, supports 360° omnidirectional verification.
Allows free input/output of fingerprint data.
Easy communication via UART or USB.
Processor goes into sleep mode and wakes up when detected, thus low power consumption.
Includes extensive documentation and examples for Raspberry /STM32 (Software on PC, development SDK, tools some in Chinese see Waveshare Wiki).
