You posted a picture with a bunch of colored lines connected to a green board. I do not have a clue as to how it gets its power. A schematic is much more useful than a frizzy picture. Try to draw the schematic yourself. You cannot find the PN532 and you purchased one how will i find one. I found several boards that answer to PN532 but which one? I am not good at pretend games, I usually lose.
