In either case, I agree there seems to be no documentation for the ramps for due from that supplier. I know some have modified the normal ramps for DUE, but they show no pictures of the modifications. I like the DUE because it can use a relatively inexpensive. ~20$, the due has much more processing power than a mega, while still going with a modular board setup, which lends itself more to hacking and less expense if it goes bad. ~35bux for a bad board vs ~100-200$USD for a bad all in one controller.
