CNC Shield V3 Engraving Machine Expansion Board A4988 Driver Expansion Board for Arduino 3D Printer CNC A4988 CNC Shield V3 Engraving Machine Expansion Board: Compatible A4988 or DRV8825 stepper drivers Input Voltage: 12-36V DC 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. 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. GRBL 0.9 compatible.
