Specifications

Key Features

• High-Resolution Optical Sensor: 500 DPI imaging captures detailed fingerprint patterns for accurate enrollment and matching.
• Onboard DSP Processing: Built-in processor handles fingerprint image capture, feature extraction, template generation, and matching-no external processing required.
• Large Template Storage: Internal flash memory stores up to 1,000 fingerprint templates, enabling standalone operation without a host database.
• Fast Verification: Completes 1:1 matching in under 1 second and 1:N search efficiently across the stored database.
• Ultra-Low False Acceptance Rate: FAR below 0.001% ensures robust security against unauthorized access.
• Simple UART Interface: 4-wire serial connection (VCC, GND, TX, RX) makes integration straightforward with virtually any microcontroller.
• 3.3V Logic Level: Directly compatible with 3.3V platforms like ESP32 and Raspberry Pi; works with 5V Arduino boards via the included wiring harness.
