Compact, low power fingerprint module with fast, reliable recognition Why choose this module Small footprint and low power consumption make it easy to integrate into embedded systems and compact devices. Fast recognition and fast fingerprint search reduce user wait time and improve system responsiveness. Robust performance with good adaptability to both wet and dry fingers improves realworld reliability. Key features Integrated design: sensing window and fingerprint processing components combined in one compact module for simpler system integration. performance algorithm: extracts fingerprint features for storage, comparison, and search. Supports both registration and matching workflows. Matching is handled as either direct comparison or broader search. Dual communication interfaces: USB and UART for flexible connection to microcontrollers, single board computers, and PCbased systems. Low power: typical supply current under 60 mA at 3.3 V. resolution: 500 dpi optical resolution for accurate feature extraction. Durable material: ABS housing. Sensor window area: 15.3 x 18.2 mm for reliable finger placement. Compact length: approximately 48 mm (1.89 inches). Technical specifications Material: ABS Resolution: 500 dpi Supply current: less than 60 mA Supply voltage: 3.3 V Window area: 15.3 x 18.2 mm Communication: USB and UART Length: approx. 48 mm / 1.89 inches How it works Registration: the module captures a fingerprint, extracts feature data, and stores the fingerprint template. Matching: when a fingerprint is presented, the module extracts features and performs either a templatetotemplate comparison or a database search to identify a match. All storage, comparison, and search operations use extracted fingerprint features rather than raw images, improving speed and storage efficiency. Typical applications Access control and door entry systems for offices, labs, and secure rooms. Time and attendance terminals and workforce management devices. Embedded devices, IoT projects, and custom electronics requiring biometric user authentication. Package contents 1 set fingerprint module Notes Allow 1 to 2 cm measurement variation due to manual measurement. Actual product color may vary slightly from images due to display differences.
