ADH-Tech GT-521F52 Optical Fingerprint Scanner with JST SH Connector

2. Short Description

High-performance 450 DPI optical fingerprint module with 3000-template storage. Features a "Wake up on Finger" touch interface, ARM Cortex-M3 processor, and dual UART/USB connectivity.

3. Product Description (Long)

The GT-521F52 is a professional-grade biometric solution designed for high-security applications requiring fast and accurate identification. Powered by an ARM Cortex-M3 MCU, this module handles all complex fingerprint algorithms and image processing on-board. It is engineered to operate as a USB mass storage device, simplifying driver management and allowing for easy secondary development.

Precision Sensing and Durability This module features an ultra-thin optical sensor with a high-hardness anti-scratch surface ($\ge$ 5H). The sensor is optimized to work reliably even with difficult fingerprints, including dry, moist, or rough textures. With a resolution of 450 dpi, it provides stable imaging for both security and convenience.

Advanced Power and Integration A standout feature is the integrated Touch Interface, which allows the module to be woken up simply by touching the metal frame of the sensor. For integration, the module provides a simple UART protocol and complies with USB 2.0 full-speed specifications. It allows for comprehensive data control, including reading/writing templates and downloading fingerprint images from the device.

Key Features

• Massive Storage: Capable of storing up to 3000 unique fingerprint templates.

• High-Speed Identification: Achieves 1:N identification in less than 1.5 seconds.
