PRODUCT NAME
GT521F32 Optical Fingerprint Scanner

PRODUCT DESCRIPTION
The GT521F32 Optical Fingerprint Scanner is a standalone biometric module designed for secure and efficient fingerprint identification. Equipped with a high-resolution optical sensor and an in-built processor, it can capture, store, and match fingerprints without requiring external processing. The module communicates with microcontrollers and other devices through a UART (serial) interface, making it compatible with platforms such as Arduino, Raspberry Pi, and other embedded systems. It supports both 1:1 and 1:N fingerprint matching, enabling verification and identification of multiple users. With a storage capacity of up to 200 fingerprints, fast recognition speed, and the wake-on-finger feature, the GT521F32 provides a seamless and reliable user authentication experience. Its compact design, low power consumption, and high accuracy make it ideal for access control systems, security devices, attendance management, and DIY biometric projects.

KEY FEATURES
The GT521F32 features a high-quality optical fingerprint sensor capable of capturing clear and detailed fingerprint images. Its in-built processor allows independent processing, eliminating the need for external computation. The module can store up to 200 unique fingerprints and supports fast recognition, providing quick user verification. It allows both 1:1 matching for verification and 1:N matching for identification among multiple stored fingerprints. Communication is handled via UART serial interface, ensuring easy integration with microcontrollers and embedded systems. The scanner includes a wake-on-finger function for energy-efficient operation, consuming minimal power during standby. Designed for reliability and high accuracy, it is suitable for security applications, access control, time attendance systems, robotics, and various Arduino or Raspberry Pi projects.
