The main features of the fingerprint reader module

  • Also suitable for beginners - easy to use with a few simple commands, no knowledge of fingerprint technology or the internal structure of the module required
  • Commercial fingerprint algorithm, stable performance, fast identification
  • Very sensitive detection, it is enough to lightly touch the identifying area (without pressing) to trigger the reader
  • Highly integrated hardware, processor and sensor in one small chip, suitable primarily for small size applications
  • Allows you to freely input / output fingerprint images, fingerprint function files and other fingerprint related activities
  • Equipped with a built-in UART connector, easy to connect to hardware platforms such as STM32 and Raspberry Pi

Pinout description

  • VIN - power pin 3.3 V
  • GND - the ground of the system
  • RX - serial data input (TTL level)
  • TX - serial data output (TTL level)
  • RST - RESET pin, sleep control interface:
    • high level: module power supply - start
    • low level: module shutdown - sleep
  • WAKE - wake up pin, when the RST pin is in the low state (sleep), the module will be activated, when the finger touches the collector surface, it will go high
