I noticed the jumpers next to the .1" dual row connector in the lower right. My guess is that the jumpers select which input signals to use for step/dir. Each additional card needs to be jumpered to different inputs. So this is a two channel step/dir board (?). If this is the case, there needs to be two sets of motor output leads.
