I bought a couple of Scoops to test out. I was hoping to swap my voltage regulator and capacitors with only the scoop. The input power is 6V Alkaline batteries (4.4-7.2V, discharged-full charged, or multiple parallel packs of 4xD-cells in series). I am using the Notecarrier A for this project (since I need external SIM). Can I power the Notecarrier A on VIO (to skip the onboard voltage regulator) or should I use V+?
