Capacitive Fingerprint Reader, Onboard Processor STM32F105


Part Number:Capacitive Fingerprint Reader

Date:2020/08/27 11:03

The Capacitive Fingerprint Reader is a standard fingerprinting module designed for secondary development, allows fast and stable fingerprint verification.
Based on a high-speed digital processor STM32F105R8, combined with high-security commercial fingerprinting algorithm, and advanced semiconductor sensor, the Capacitive Fingerprint Reader becomes a simple but smart integration module, provides functionalities like fingerprint enrolling, image processing, feature finding, template generating and storing, fingerprint matching and searching, etc.


  • Easy to use by some simple commands, you don't have to know any fingerprint technology, or the module inter structure/calculation
  • Commercial fingerprinting algorithm, stable performance, fast verification
  • Sensitive detection, just touch the collecting window lightly, without pressing
  • Allows to freely input/output fingerprint images, fingerprint feature file and other fingerprinting actions
  • Dual communication, UART or USB
  • Processor will enter sleep and wake up when detecting, achieves low power consumption
  • Comes with rich related resources (software on PC, development SDK, tools, and examples for Raspberry/Arduino/STM32)


  • Fingerprint lock
  • Fingerprint safe deposit box
  • Access control system
  • Clock in and out
