Description
The R307 Optical Fingerprint Sensor is a standalone biometric module designed for fingerprint detection, verification, and identification systems. It integrates an optical imaging sensor with a high-performance DSP processor that handles image acquisition, feature extraction, and template matching internally. The module communicates via TTL UART interface and supports direct fingerprint enrollment and storage in onboard Flash memory. With a 500 DPI resolution sensor and built-in red LED indicator, it ensures accurate image capture and reliable operation. Suitable for access control, safes, attendance systems, and embedded security projects.
