I have some pololu motor shields that are labeled "H4988", which looks significantly different from the a4988 model on their website. I am trying to set the potentiometer, but I can't for the life of me figure out where the negative end of my multimeter should go. Can anyone show me a pin diagram of this board? Or find an equation for setting it's Vref? Would be much appreciated. Thanks!

I'm on my second account again, i got signed out, and now I can't sign in with steam. Any ideas? EDIT: I thought this was the wrong subforum so i edited it to say so, turns out it was right and im just tired and can't tell where i'm posting. Moral of the story? Don't post on minimal sleep, kids.
