Advanced Fingerprint Module for Arduino


Out of stock

This is advanced, high quality optical fingerprint verification module with TTL interface. It consists of optical fingerprint sensor, high performance DSP processor and Flash. It has many functions such as fingerprint Login, fingerprint deletion, fingerprint verification, fingerprint upload and download.

User can easily develop powerful fingerprint verification application systems based on the rich collection of controlling command provided by the module.

High Adaptation to Fingerprints 

When reading fingerprint images, it has self-adaptive parameter adjustment mechanism, which improves imaging quality for both dry and wet fingers. 

Algorithm with Excellent Performance 

The module algorithm is specially designed according to the image generation theory of the optical fingerprint collection device. It has excellent correction & tolerance to deformed and poor-quality fingerprint. 



  • Operating Voltage:                  4.3 : 6VDC
  • Maximum Voltage:                  6.5V(exceeding this value will cause permanent damage)
