Hi all,

Has anyone had any success with connecting two A4988 boards to a single arduino board? If so, any guides as per how to do it?

Thanks

It's so easy that I don't understand your question. Each board just needs a connection for step and direction. The Pololu page shows the wiring diagram that I use. Pololu - A4988 Stepper Motor Driver Carrier

You can even share the direction pins if you want to save a pin - so long as you don't
step both A4988's simultaneously. The direction pin is only sampled when the step
pin has a rising edge.
