i know the 3.6 isnt 5v tolerant, but if I wanted to drive a single common anode RGB LED with minimal part count whose forward voltage is very close to 3.3v (3.1v it seems from the data sheet), could I hook the common anode to 5v (Vin) and then the 3 cathodes (thru current limiting resistors) to digital output pins, even tho they will only go from 0-3.3v. my thinking is- the forward voltage on the red led is 1.8v, but the G/B is over 3.1v - feels a bit close to 3.3v? so I was thinking it might be ok if the anode was 5v, as the drop across the LED means that the pin would never see more than 5-1.8v which is under 3.3v. am I going mad?
should I just run it off 3.3v at the anode and be happy?
sorry for the dumb question.
