This expansion board, as a driver expansion board, can be used for engraving machines, 3D printers, and CNC. It has a total of four slots and can drive four A4988 stepper motors. Each road stepper motor only needs two IO ports. In other words, six IO ports can be well managed with three stepper motors. The CNC shield V3 for Engraving Machine 3D Printer A4988 DRV8825 driver expansion board is very convenient to use. After inserting Arduino CNC Shield V3.0 into Arduino UNO, and installing GRBL firmware then you can quickly make a CNC engraving machine
