*Disclaimer: The images are merely illustrative.
A capacitive fingerprint reader developed by Waveshare. The reader module is equipped with a connector microUSB and UART interface. It is based on a high performance Cortex processor with commercial high security fingerprint algorithms and an advanced solid state fingerprint sensor. The module is designed as an intelligent module to extend the capabilities of the design with fingerprint capture, image processing, template generation and storage, matching and fingerprint search. Powered by 3.3 V to 5 V.
Easy to use with a few simple commands
Commercial fingerprint algorithm, stable performance, fast identification
Sensitive detection, just lightly touch the identification area, no pressure
Allows free input / output of fingerprint images, fingerprint function files and other fingerprint activities
Dual communication, UART or USB
Module is equipped with microUSB port and 5-pin connector for UART communication. It is powered by 3.3 V or 5 V. Its leads are:
VCC - supply voltage 3.3 V or 5 V
GND - ground
TX - UART transmitter line
RX - UART receiver line
RST - RESET pin
