Beginner FPGA and Stepper motor

I have a question about FPGA and stepper motor

I want to make use of the output voltage of FPGA to provide the voltage for stepper motor.

However, i have no idea how to connect them tgt.

I have checked the date sheet. And there is a GPIO that i THINK it can be used to provide 3.3V for stepper motor.

But when i come to verilog and assign pin number for output(for stepper motor). I dont can't find any pin for it.

The question is , the 3.3V which is written on the green board. Is that a constant voltage that when u connect with any device , it provides 3.3V? Thank you.
