I had 5 made. They just arrived. I'm trying to find some connectors, because I prefer not to reuse the old ones. If I get the board working, I might be willing to sell a couple of the remaining board to recoup some of my cost.

Why not? Is there some motor to inverter communication that's missing?

Sounds good! I'll keep posting information as I move forward and I'll take whatever help I can get.

I'm going to convert some type of Jeep vehicle from the mid to late 90s or early 2000s using a 2009 Chevy Tahoe Hybrid transmission. I don't have the vehicle picked out yet. I'm trying to develop the powertrain right now.
