The R305 Fingerprint Module is an advanced optical fingerprint sensor designed for secure and reliable biometric identification. With its built-in TTL UART interface, this module can seamlessly interface with microcontrollers and PCs (via a level converter like MAX232), making it ideal for access control systems, time attendance devices, and security applications.

Features:

• Power Supply: Operates on a DC voltage of 3.6V to 6.0V, providing flexibility for various applications.
• Interface:
  • UART (TTL logic level) for direct microcontroller connections.
  • USB 1.1 compatibility via additional hardware.
• Modes:
  • 1:1 Mode: Matches a single fingerprint for verification.
  • 1:N Mode: Searches across multiple stored fingerprints for identification.
• Baud Rate: Adjustable from 9600 * N bps (default N=6, 57600 bps).
• Quick Image Capture: Captures fingerprint images in less than 0.5 seconds.
• Storage Capacity: Stores up to 256 unique fingerprint templates.
