Characteristics：
1.DC power input type:12V~36VDC
2.Output current:0.21A-1.5A
Mircostepping：1(1.8º)、1/2、1/4、1/8、1/16、1/32、1/64、
3.Dimensions：100mm×59mm×19mm
4.Weight：<200g.
5.Working environment：Temperature-15～40℃
I/O Ports：
1.VCC：DC power positive pole
Note:Must guard against exceeding 36V,
so as not to damage the module
2.GND：DC power cathode
3.A+、A-：Stepping motor one winding
4.B+、B-：Stepping motor other winding
5.CP ：Stepping pulse input
6.DIR：Stepping motor direction input
7.+5V：power supply port for inside optical coupling
8.ENA: 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
