Well, I let the magic smoke out. Last night I accidentally hooked up VIN & GND backwards with a 9v and it went poof!
Silly question, but, I just wanted to make sure should have been expected.
Unfortunately, the only reverse battery protection on the April is available at the P+,P- pins. Applying reverse power to VIN will let the smoke out. 
Okay, that’s what I figured. I guess that’s what a software guy gets when he’s sleep deprived and not paying attention.
On that note - looks like I gotta by me a couple of Aprils.
Edit: it isn’t a problem to sell impees, is it? I have a Hannah I’d like to get rid of - I forget if they’re tied to any account or anything.
Nope. Thats what we do at MakeDeck. 
When another user BlinksUp the Imp in the Hannah to their account it should move from yours to theirs.
Cool - thanks!
