Haha, I wish it was that simple as having everything the same voltage ;) 
Unfortunately, most of my sensors run at 5v, so it's either doing level 
shifting on 30+ sensors, or on one connection between the Arduino and BBB.

To be honest, if I'd been able to run everything at 3v3, I'd have gotten a 
Due and a BBB, then there wouldn't have been problems at all :)
