CNC shield V3 for Engraving Machine 3D Printer A4988 DRV8825 driver expansion board Ceramic 19 Active Low Enable (OE')This CNC shield V3 driver expansion driver board can be used for engraving machine, 3D Printers, CNC etc. This board has four slots which 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. After insert Arduino CNC Shield V3. 0 into Arduino UNO, Installed GRBL firmware then you can quickly DIY a CNC engraving machine. Features: Controller each
