ADH-Tech GT521F32 Optical Fingerprint Scanner Module with JST SH Connector
The ADH-Tech GT521F32 is an optical fingerprint scanner module featuring a 32-bit ARM Cortex-M3 processor for on-board template processing. It communicates via UART (3.3V logic) and USB 2.0 full-speed, offering a storage capacity of 200 fingerprints for secure access control and identification systems.
Features
- Optical sensor with 450 DPI resolution and 258 x 202 pixel image capture.
- On-board processing by 32-bit ARM Cortex-M3 MCU for fast 1:1 verification and 1:N identification.
- Stores up to 200 fingerprint templates with a low False Acceptance Rate (<0.001%).
- Wake-on-touch function via metal frame contact for low-power operation.
- Durable 5H hardness scratch-resistant surface for reliable performance.

The GT521F32 module utilizes an optical scanning principle, capturing a visual image of a fingerprint through its integrated digital camera. It is designed to perform reliably with dry, moist, or rough fingerprints, making it suitable for various environmental conditions. The module processes the captured image on-board using its embedded ARM Cortex-M3 processor, converting it into a compact 496-byte template for secure storage and comparison.
Communication is facilitated through a simple UART interface (3.3V TX/RX levels) and a full-speed USB 2.0 port, requiring an external UART-to-USB converter for direct PC connectivity. The module operates from a 3.3V to 6V DC supply, drawing less than 130mA during active scanning, and features a wake-on-touch function that activates the system when a finger contacts the sensor’s metal frame, optimizing power consumption.
