Square Capacitive Fingerprint Sensor Module (UART TTL)
Availability:
In stock
The Square Capacitive Fingerprint Sensor Module is a compact biometric fingerprint recognition module that integrates a capacitive fingerprint sensor with an internal fingerprint processing algorithm. It communicates with a host microcontroller through a UART TTL interface and supports fingerprint enrollment, template storage, fingerprint matching, and identification. Its compact square form factor and low-power design make it suitable for embedded security and biometric applications. The module is designed for easy integration with microcontrollers and electronic control systems where fingerprint authentication is required.
