@3ddab33a Thanks for the rundown. What stands out for me though is the weird choice for a rather wasteful 5V/5A power delivery. Wouldn't it have made more sense to use USB PD with say 12V/2.1A at that point? I guess the 'trading efficiency for cost' compromise also applies here if it is that much more expensive to implement. 

 @3bd42c0d Yes, though I'm guessing that's more to save on BOM/board space for stepdown voltages. Maybe they'll go to 12v for a new revision someday, I'd be happy about that.

Note their PSU provides 12v/2.25A...
