CNC Shield V3 3D Printer Expansion Board For Arduino UNO R3 & MEGA

Feature:

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.
