Description

This expansion board as a driver expansion board, can be used for engraving machines, 3D printers.
nIt 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.
