JOY-IT R301T Optical Fingerprint Sensor Module with UART Interface, 1000 Templates, 500 DPI, Blue LED

Store up to 1000 fingerprint templates with the JOY-IT R301T optical fingerprint sensor module. It captures high-resolution 500 DPI images over a 14.5 x 19.4 mm scanning area and communicates via UART at up to 115200 bps. The integrated blue LED provides visual feedback during enrollment and matching.

Overview

The R301T is a compact optical fingerprint module designed for integration into access control systems, time attendance terminals, and DIY security projects. It operates from 3.3V to 6V DC and draws less than 60 mA in typical operation, making it suitable for battery-powered devices. The module supports both 1:1 verification and 1:N identification modes with adjustable security levels from 1 to 5.
