V3 Engraver 3D Printer New CNC Shield Expansion Board A4988 Driver for Arduino Description: 100% brand new and high quality This expansion board as a driver expansion board, can be used for engraving machines, 3D printers. It is a total of four slots, can drive four A4988 stepper motor. Each road stepper motors only need two IO ports. In other words, six IO ports can be well managed three stepper motors. Very convenient to use. UNO for Arduino module IO port correspondence introduction.

Stepper motor wiring as follows: 2A, 2B is a group (red, green), 1A, 1B is a group (blue, yellow), if want to change direction, can be change the position of one group , for example 2A, 2B mutually exchanged.
