Product Description
The GT521F52 Optical Fingerprint Scanner Module is a compact, high-speed biometric recognition device engineered for secure authentication and identification applications. Utilizing a high-resolution optical sensor, this module captures fingerprint images with exceptional accuracy and speed, making it ideal for systems requiring fast and reliable access control.
Equipped with a power-efficient ARM Cortex-M3 processor, the GT521F52 performs onboard image processing, template creation, storage, and matching operations—all without requiring an external processor. With storage capacity of up to 3000 fingerprint templates, it significantly enhances scalability for multi-user systems.
This module communicates via a simple UART interface (3.3V logic) and supports USB connectivity (via UART-to-USB converter), ensuring seamless integration with microcontrollers, embedded systems, or PCs. Its “Wake-on-Finger” touch detection, anti-scratch surface, and robust performance on dry, moist, or rough fingerprints make it a trusted choice for security-focused projects.
