Apologies for dragging this thread out of hte grave, however seemed the most pertinent thread out of the ones I've found.
In terms of wiring the 5v supplies can the 4 be wired to the same 5volt source?
I'm waiting on a couple of components, and the stepper I have is 5volt, so I assume that they can all come off the 5 Volt source on the board?
Also, in terms of running steppers, how many feasibly can be run off one Arduino before processing becomes too much. the inputs share common earth, so each one has one input
Cheers, and apologies for the newbie question, it's my first foray into stepper motors
