    Description

    The R308 Biometric Fingerprint Sensor Module is a compact and reliable fingerprint identification solution designed for secure access control, attendance systems, and embedded authentication projects. It integrates an optical fingerprint sensor, a high-speed DSP processor, and onboard flash memory to provide fast and accurate fingerprint capture, storage, and matching. Because it supports both 1:1 verification and 1:N search modes, it offers flexible implementation for small and medium-scale systems. Moreover, the module stores up to 500 fingerprint templates internally, reducing the need for external memory management. With UART (RS232 TTL level) communication, it connects easily to Arduino, ESP32, STM32, Raspberry Pi, and other development platforms. Featured By RoboticsBD.
