Optical Fingerprint Sensor Module (UART, 1000 Fingerprints)

The Optical Fingerprint Sensor Module is an integrated biometric scanner designed for identity verification and access control projects. Equipped with onboard DSP processing and storage for up to 1000 templates, it is ideal for makers, students, and engineers developing secure embedded systems.

Onboard DSP processing

The module features an integrated digital signal processor that handles image acquisition, feature extraction, and template generation directly on the hardware.

1000-template internal storage

Onboard memory stores up to 1000 fingerprint profiles locally, removing the need for external database management in standalone installations.

Flexible biometric matching modes

It supports both 1:1 verification against a specific record and rapid 1:N identification across the entire stored template library.

TTL serial communication

The standard UART interface enables direct integration with microcontrollers and embedded development boards via straightforward serial commands.
