Mechanical dimension:

I\/O Ports:
1. VCC+ DC power positive pole
Note:Must guard against exceeding 50V，
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 PUL+ PUL -:Stepping pulse input+5V (Rising edge effective，rising edge duration !#!amp!*!gt;10!#!amp!*!mu;S)
6 DIR + DIR-:Stepping motor direction input， voltage level touched off，high towards， low reverse
7 ENA+ ENA-: motor free Usage:Mainly suitable for 42HS， 42BYG， 57BYG， 57HS41， 57HS56， 57HS76 stepper motor.Suitable for two phase motor which current is below 4.5A.
