Overview
The Capacitive Fingerprint Reader (B) is a fast and stable capacitive fingerprint module specialized for secondary development, and suits integration applications.
By incorporating a high-performance Cortex core processor, high-security commercial fingerprint algorithm, and advanced semiconductor fingerprint sensor, this module is designed as an intelligent integration module with functions including fingerprint enrolling, image processing, 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 identification.
- Sensitive detection, just touch the collecting window lightly, without pressing.
- Allows to freely input/output fingerprint images, fingerprint feature files, and other fingerprinting actions
- Dual communication, UART, or USB.
- Comes with complete resources, manual, related tools, and Raspberry/Arduino/STM32 demos.
