One last question regarding steppers.

I am looking at the Pololu DRV8825 stepper motor drive rated for 1.5A
without a heatsink or 2.2A with cooling.  The nema 23 steppers that I've
found are mostly 2.8A.  Is that the coil max amp rating or what it draws
when driving it (clearly I know little about steppers)?  I'm guessing this
will overload the DRV8825.
