Each person’s fingerprint is unique, just like DNA, you can use fingerprint to replace your key, or lock your computer with fingerprint. Adding fingerprint to your project makes it awesome, UART Fingerprint Reader is the new product we want to introduce you!
UART Fingerprint Reader is a fingerprinting module which integrated STM32F205 as its processor, less power consumption, stable and powerful! It is an intelligent module that provides many functions like fingerprint recording, image processing, eigenvalue extraction, fingerprint matching and searching, etc.
If you want to communicate with PC, CP2102 USB-TTL module is a good choice.

Note: Just put finger on the window sightly when register your fingerprint, don’t press the window hardly.
Note: The on-board mini USB port only used to update module’s firmware, don’t use this port to power module when module is in working mode!
