Ya, a PA board is all that’s inside an HD-LM or a Smartech II. PA6 for 1/6hp DC motor and PA7 for 1/2hp AC. But those are just what’s typical. Either board will run an AC or DC motor, the PA7 is just a bit beefier.
The only thing I’m not sure on is I’ve only seen those on TK equipment. The PA board and AAR1 are on the CAN channel. I’m almost positive they will communicate with each other independent of the controller, Just never seen it. I think I have the parts on my van though, I’ll see if I can test it out over the weekend.
