The Fingerprint Module with TTL Serial Communication is a powerful and versatile fingerprint scanner designed for easy integration into various projects. Operating at 3.3v TTL, this module communicates over TTL Serial, making it compatible with many devices. However, for 5v devices like the Arduino Uno, a logic-level converter or resistor divider circuit is required.

Features:

• TTL Serial Communication: The module communicates over TTL Serial, simplifying integration into projects and allowing easy embedding into your next electronic endeavor.
• Voltage Compatibility: Operates at 3.3v TTL, requiring a logic level converter or resistor divider circuit when connecting to 5v devices such as the Arduino Uno.
• Onboard Optical Sensor and 32-bit CPU: The module handles the intricate process of reading and identifying fingerprints with its onboard optical sensor and powerful 32-bit CPU. This offloads the heavy lifting from the connected device.
• Simple Command Interface: Sending simple commands to the module is all needed to register fingerprints. The onboard processor takes care of the complex fingerprint analysis.
• Fingerprint Database Management: Capable of storing up to 2000 different fingerprints. The fingerprint database can be downloaded from the module and distributed to other units.
• 360° Recognition: The module is equipped with 360° recognition capability, enhancing its accuracy in fingerprint identification.
• Fingerprint Image Retrieval: Beyond fingerprint templates, the module allows users to retrieve fingerprint images and even pull raw images from the optical sensor.
• 1:1 Verification and 1:N Identification: Supports 1:1 verification and 1:N identification, providing flexibility for various security and identification applications.
• Compact and Easy to Mount: With dimensions of 37 x 17 x 9.5 mm, the module is small and easy to mount. Two mounting tabs on the side facilitate secure attachment.
• JST-SH Connector: The onboard JST-SH connector features four signals - Tx, Rx, Vcc, and GND, simplifying the wiring process.
• Demo Software for PC: Demo software for PC allows easy connection to your computer using an FTDI Breakout. This facilitates the reading and management of fingerprints.
