I/O Ports：

1.GND,：VDC+: it input DC power Note:Must guard against exceeding 36V, so as not to damage the module2.A+、A-：Stepping motor one winding 3.B+、B-：Stepping motor other winding4.PUL ：Stepping pulse input5.DIR：Stepping motor direction input6.VCC：power supply port for inside optical coupling7.EN: motor free

NOTE：

1. When ambient temperature is high or working current over 1.05A, fix the module on big metal shell , or use axle flows fan dispels the heat, to make the module run reliably for a long time. 2. Half current automatically: if control machine not send out signal in half second, driver enter half current state of automatically for electricity saving, the phase current of the winding of the electric
