Hey guys,
I blew all 4 of my A4988 drivers last week by accidently plugging the chips in backward. I was following a picture on the RepRap wiki that showed them plugged in that way (of course there was a note under it that said they were backward that I did not see)
Anyway I ordered 4 new boards and I am trying to be extra cautious when they arrive. Here is a link to my Stepper Motor datasheet.

I have the motor connected as follows.
yellow - 2B
Blue - 2A
Red - 1A
Green - 1B
Is this correct?
Also one of the drivers I blew seems to work a bit but it just makes the stepper stutter.
