Product description: Capacitive fingerprint reader (B) - UART/USB - Waveshare 20679

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.

 

Main features of the fingerprint reader module

  1. Easy to use with a few simple commands

  2. Commercial fingerprint algorithm, stable performance, fast identification

  3. Sensitive detection, just lightly touch the identification area, no pressure

  4. Allows free input / output of fingerprint images, fingerprint function files and other fingerprint activities

  5. Dual communication, UART or USB

 

Connection of the module

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:

  1. VCC - supply voltage 3.3 V or 5 V

  2. GND - ground

  3. TX - UART transmitter line

  4. RX - UART receiver line

  5. RST - RESET pin
