Yeah sure, all pins can handle 0..3.3V (and some up to 5V).What you're describing sounds a bit strange, but maybe only because I don't fully understand what you're trying to do.

Hi IOIO users!Apologies if this is a silly question, I am an electronics noob, and I am worried about damaging the board.Can I jump a 3.3v pin directly to an input pin?I want to send 3.3v to a relay, then send back the 3.3v into a pin when the relay is triggered.Thanks!

Yes, that should work fine, as long as you remember to use a pull down resistor on the pin (either internal or external) to assert a valid 'low' condition when the relay is open.
Another way to accomplish the same thing, which is probably what I would do, is to have the relay pull to GND while using a pull UP on the pin. It doesn't really matter.
