I tried posting a similar question to the mailing list, but I had some email issues and am uncertain if my post actually succeeded. I wanted to update it anyway, so I'm going to try posting to the archive forum.
I have both a Tobi and a Robovero. I would rather use the Tobi, but I'm trying to get a clean analog 0-5V from either of these expansion boards. Is that possible? Even if I need to use third-party hardware, I would love some recommendations.
