Here's a rundown of three boards best suited for beginning to intermediate FPGA designers. Some boards cost thousands of dollars, and it’s unrealistic to compare a board of that cost to a board that a hobbyist would likely choose, so this comparison looks at three popular boards in the sub-$90 price point.
