Description
A+ / A-
Connect to the stepper motor phase A
B+ / B-
Connect to the stepper motor phase B
WARNING:
Incorrect connection of phase winds will permanently damage the controller!
Resistance between leads of different phases is usually > 100KΩ. Resistance between
leads of the same phase is usually < 100Ω. It can simply measured by a multimeter.
WARNING:
Except supply voltage port and motor terminal, voltage on port must be kept
between -0.3~5.3V. Otherwise, the controller will be damaged.
