R307S AS608 Optical Biometric Fingerprint Scanner
R307S / AS608 optical fingerprint biometric scanner with fast recognition and UART interface—ideal for access control, attendance, and security applications.
Description
The R307S / AS608 Optical Biometric Fingerprint Scanner is a reliable and high-accuracy fingerprint identification module designed for secure biometric authentication systems. Using advanced optical fingerprint sensing technology, it captures clear fingerprint images and performs fast and accurate matching.
This module features an onboard DSP processor and flash memory for storing fingerprint templates, enabling standalone operation without the need for external image processing. It communicates via a UART (TTL) serial interface, allowing easy integration with Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller platforms.
With quick fingerprint enrollment, low false acceptance rate, and durable optical sensor construction, the R307S / AS608 scanner is ideal for access control systems, attendance machines, smart locks, security devices, and embedded biometric projects.
