I'm interested in working with the ChipKIT Max32 because of its speed, Number of I/Os, and Memory. All awesome!

As I'm reading I see that the output voltage is 3.3v. So that led me to try and find some some relays that would work.

I found a alot of 5vdc Relay Opto Isolators like:

but no luck in 3.3v.

I need to power some 24vdc and 120 vac controls and via a relay is most logical.

Any ideas?

All you need is a transistor, a diode and a resistor. No need for anything fancy. The basic driving circuit for running a relay from an arduino works the same at 3.3v or 5v.

Thanks for the info.
