Yay, 5V tolerant! A nice bag of goodies

Note the word tolerant - make sure it's powered up when applying 5v to the GPIOs or phut.

.

Is A2 5V tolerant or only A4?

I believe 2 is as well - we just spent the time testing and qualifying. Note this means input can go to 5v (as long as the chip is powered), but output is still 3v3.
