GT521F52 Optical Fingerprint Scanner Module

The GT521F52 Optical Fingerprint Scanner Module, equipped with a JST SH connector, is a high-performance device ideal for applications in access control, security, identification, and convenience. This optical sensor module is designed for seamless integration, featuring a serial interface (UART) that requires only two wires for TX and RX communication, along with two additional wires for a 5V power supply. The primary distinction between the GT521F32 and the GT521F52 models lies in their fingerprint storage capacity.

As an optical scanner, the GT521F52 captures visual images using a digital camera, and it is activated by a finger touching the metal frame of the sensor. The module processes fingerprint images on-board using a low-power 32-bit ARM Cortex-M3 processor, converting them into strings of data known as templates. These templates are stored on the module, which is configured as a USB mass storage device, enabling easy sharing and enrollment of multiple users through a database network with other modules. This functionality makes the GT521F52 an effective choice for environments requiring robust biometric authentication.
