CNC Shield Engraving 3D Printer Expansion Board For Arduino Uno

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 / DRV8255 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.
