Feature
●This expansion board can be used as a drive expansion board for engraving machines, 3D printers, etc. There are a total of 4 slots for stepper motor drive modules.
●It can drive 4 channels of non-feeding motors, and each stepper motor only needs 2 IO ports.
●6 IO ports can manage 3 stepper motors well, which is very convenient to use, bid farewell to the cumbersome operation of traditional stepper motors.
●When inserting the A4988 module, be careful not to insert it in reverse. The wiring method of the stepper motor is as follows, 2A, 2B are a group (red, green), 1A, 1B are a group (blue, yellow).
