Round All-in-one Capacitive Fingerprint Sensor (C) _BF25_10 Optional working modes: TCP Server/This is a round, all in one capacitive fingerprint sensor module, which is nearly as small as a fingernail. The module is controlled via UART commands and is easy to use on popular development platforms such as the Raspberry Pi. Its advantages include 360 omnidirectional verification, fast verification, high stability, and low power consumption, etc. Based on a high performance Cortex processor, combined with a high security commercial fingerprinting
