This is R305 Fingerprint Identification Module Fingerprint Lock Optical Development Board with TTL UART interface for direct connections to microcontroller UART or to PC through MAX232 / USB-Serial adapter.
 
The user can store the fingerprint data in the module and can configure it in 1:1 or 1: N mode for identifying the person. 
The FP module can directly interface with 3v3 or 5v Microcontroller. 
A level converter (like MAX232) is required for interfacing with PC serial port.
