ADH-Tech GT521F52 Optical Fingerprint Scanner Module with JST SH Connector
The ADH-Tech GT521F52 is an optical fingerprint scanner module featuring a high-resolution 450 DPI sensor and an integrated ARM Cortex-M3 processor for onboard template processing. It communicates via a simple UART interface (3.3V logic) and is compatible with 3.3V to 6V power supplies, making it suitable for integration into access control systems, security devices, and embedded projects.
Features
- High-resolution 450 DPI optical sensor for precise fingerprint imaging.
- Onboard ARM Cortex-M3 processor handles enrollment, verification, and 1:N identification.
- Large storage capacity for up to 3,000 fingerprint templates.
- Simple UART serial interface (3.3V logic levels) for easy microcontroller integration.
- Wide operating voltage range from 3.3V to 6V DC.

The GT521F52 module utilizes an optical scanning method to capture a high-quality digital image of a fingerprint. The integrated 32-bit ARM Cortex-M3 microcontroller runs advanced fingerprint algorithms to process the raw image, extract unique features, and generate a compact 496-byte template. This onboard processing enables fast 1:1 verification and 1:N identification without burdening the host system.
Designed for robust performance, the sensor features an anti-scratch surface with a hardness rating of ≥5H and is engineered to work reliably with dry, moist, or rough fingerprints. The module supports a wake-on-touch function via its metal frame, conserving power when idle. Communication is handled through a straightforward UART protocol, requiring only TX, RX, and power connections.
