Another option for controlling your stepper motors. Very easy to use with arduino, just join CLK- and CW- to ping GROUND, CLK to STEP pin and CW to DIR PIN. You can select the number of microsteps and the current of you motor as well.
This is an excellent driver! Works perfect on my 5 axis breakout board and nema17 stepper motors. Did I mention the price? Can't find better on the planet. Thanks Banggood.
