Description
We're now connecting the Pololu VDD to +3v3 in Rev1..Rev3. Is this correct? Shouldn't it be connected to +5V?
Anybody wants to comment on this? See specs: http://www.pololu.com/file/0J450/a4988_DMOS_microstepping_driver_with_translator.pdf

3.3V sounds right to me - this determines the logic levels, and since the ARM operates at 3.3V, that wil make things match up.
