HI.

I'd like to connect between xilinx FPGA (SMPS 5V 2A Adaptor)and small board( USB 3.0 power)
But I want to know that how to connect two boards in the different power source.
Would you please let me know how to resolve in this situation?

Whatever the connector you choose, the ground reference must be the first conductor to be connected.

Look at the required logic levels... you may need a level translator, and a separate PSU if you need to generate 3V3 for the USB board.....
