R305 Fingerprint Module

R305 fingerprint module is a fingerprint sensor with TTL UART interface for direct connection to microcontrollers via UART or to PC through MAX232 / USB-Serial adapter.

The user can store fingerprint data in the module and configure it in 1:1 or 1:N mode for identifying a person. The module can directly interface with 3.3V or 5V microcontrollers. A level converter (like MAX232) is required for interfacing with PC serial ports.

It is an optical biometric fingerprint reader that can be embedded into various products such as access control systems, attendance systems, safety deposit boxes, and car door locks.

Features

• Integrated image collecting and algorithm chip (ALL-in-One)
• Can be embedded into various end products
• Low power consumption, low cost, small size, excellent performance
