The AD-013 fingerprint sensor module is consist from a fingerprint sensor & a MCU. The module provide one UART interface output port for connecting to customer side main board.


The operation of AD-013 is as following, a fingerprint image captured by pixel array, delivery fingerprint ridge or valley signals to A/D converter and digital processor, then to the serial peripheral interface for data-reading. Due to MCU already installed fingerprint algorithm, the user can through UART interface use MCU SOC command to operate module like fingerprint enroll, match operations etc.
