Maybe the answer to this question will help my problem go away: is there a way to power just the Arduino and have the Zumo shield and motors work? The Yun has a regulator on its mini USB connector, and I have a bunch of those “iPhone battery backup” bricks that basically are USB rechargeable regulated 5v out lipo packs. If I could plug that into the Yun and fully power the Zumo, that’d work.
