FP-SDK-3935

This is a fingure print sensor module with TTL UART interface for direct connections to microcontroller UART or to PC through MAX232 / USB-Serial adapter. The user can store the finger print 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.

PC Application

Connection of fingerprint to Microcontrollers

The fingerprint sensor can be wired as below. Do not follow color code of connector provided.
The corner pin is +5V as shown below in red line, then is Ground(GND), Then TXD which goes to MCU's RX-IN, and last pin is RXD which goes to MCU's TX-OUT pin.

Note: We test the product before shipping.  We do not provide help related to programing. All details and protocol are given in download.
