product details The extension board can be used for carving machine and 3D printer driver expansion board, there are 4 slots for stepping motor driver,it can not into the motor drive 4 road.And every step motor only need two IO interfaces, that is to say, 6pc IO interfaces can be manage three stepper motors well, it's very convenient
Note: When inserting the A4988 module, must be careful not to insert opposite
Stepper motor wiring as follows: 2A, 2B is a group (red, green), 1A, 1B is a group (blue, yellow).If you want to change direction, can be change the position of one group , for example 2A, 2B mutually exchanged.
