EasyDriver 4.4 (Stepper Motor Driver) 3D Printer Extruder Kit (Assembled with Motor) Manual axial movements for theThis is the famous bi polar stepper motor driver called easydriver. It has microstepping capability. Each EasyDriver can drive up to about 750mA per phase of a bi polar stepper motor. It defaults to 8 step microstepping mode. (So if your motor is 200 full steps per revolution, you would get 1600 steps rev using EasyDriver.) This setting can be easily overridden by tying the MS1 or MS2 pin to ground. It is a chopper microstepping driver based on the
