Getting started - pin voltages

I am just getting started on the 1769. For the GPIO pins, what voltage can they provide? Looks like 3.3v for the chip, so 3.3v? (I am powering it via 5v USB)

Is there a way to provide 5v to a GPIO pin?

A lot of inputs are 5V tolerant, but of course a 3.3 V chip can't provide 5V. Don't know what you are trying to do, but usually a transistor or FET is used to switch higher voltages :eek:

Don't tell him about the flux capacitor Zero.

Sorry, can not work with the Flux capacitor, missing my left handed wrench. Know where I can find one?
