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 :) On Thursday, May 29, 2014 4:56:38 PM UTC-5, PLyttle wrote: > > the 7-12 volt is the 'raw' power spec.
