Capacitive Fingerprint Reader - UART - USB

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.

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
