Easy driver vs StepStick A4988

I would very much appreciate if someone could walk me through the differences, or pros and cons of the Easy driver and the StepStick A4988.
I'm in the process of designing a project involving an arduino controlling up to 4 stepper motors, and will need microstepping.
I also have a good experience working with the ED, and am happy with it.
But I've only just now found out about the StepStick A4988 which is significantly smaller and would like to know if these two are exchangeable or if one has better offerings than the other.
Thanks.

The A4988 is preferred; 2000ma max vs. the A3967 at 750ma. Not much difference otherwise.

Seriously? This is quite a revelation. As far as coding, power, microstepping - no difference?
If so, am I correct in assuming that an arduino with 2 of those will be able to move 3 stepping motors
with the same control I'm used to with the ED?

Thanks

I believe you always want to use one driver per stepper. I've never seen it done or tried it otherwise; I'd expect that you'd get unbalanced power if you connected multiple steppers to one driver.

The A4988 has one extra level of microstepping available (if you wanted it). Otherwise, with respect to connecting it up and coding for it, everything is the same.

Thanks for the info :slight_smile:
