I am trying to reverse the polarity on a rather beefy motor (5 amp, 60 V) in the most simple way possible.

I need to build an H-bridge just to reverse the current, I am controlling speed elsewhere. Can I simply wire up 2 N-Channel MOSFETs and 2 P-Channel MOSFETs into a IO pin from the MCU (with resistors of course), or is it more complicated than that?

I see lots of schematics online that are different, some use diodes, some don't.

Any advice?
