Expension connector input voltage

Hello. I'd like to use my FPGA to control a little robot, but I don't know how could I gather information from outside:)... I used the expansion connector to control the servo engines (as outputs), and now I'd like to use the same ports (other pins) for input. What is the voltage level for "1" logic and what is the maximum electric current?

Thank you very much!
