Can I power the due completely via the 3.3v power pin? I have it sitting on a board where a http://www.adafruit.com/datasheets/tsr1.pdf is providing 3.3v power, but I am unable to get it to output it's CAN and I'm not sure it's doing it's i2c duties either.
If the answer is no, I have a 12v incoming supply to the TSR-1 buck converter, could I just run a wire from it to the due's VIN pin? Is there consequences to running a Due 24/7/365 in this fashion?
(I noticed from this http://forum.arduino.cc/index.php?topic=132130.0) that it "depends on current drawn" My bench power shows I'm drawing 0.07amps right now running almost everything.
Would the Due conflict with the regulated supply if I did this? seems I should disconnect the 3.3v pin if I were to power the Due this way.
