Capacitive Fingerprint Reader with STM32F105 – Waveshare

The Capacitive Fingerprint Reader with STM32F105 is an intelligent fingerprint authentication module built around a high-speed STM32F105R8 microcontroller and a high-security semiconductor capacitive sensor. It seamlessly integrates all key fingerprint functions—such as enrollment, template generation, searching, and matching—into a single compact module. The onboard processor accelerates fingerprint processing while supporting export/import of fingerprint images and templates.

This module supports both UART and USB interfaces, is easy to use with simple commands, and includes development resources (SDKs, demos for STM32, Arduino, Raspberry Pi) for rapid integration into embedded systems. It’s ideal for access control, time and attendance, smart locking, and IoT systems that require fast, reliable fingerprint authentication

Features:

• 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
