Arduino Shield on Breadboard I would like to ask if I can stack directly Adafruit PN532 RFID Shield onto my breadboard. Or do I need something for that? Thank you.
Chances are the offset headers won't allow the shield to directly plug into a breadboard. 

As @Majenko noted, shields have a header that is offset by 0.16" from the other headers. Since a breadboard is a strict 0.1" grid that header won't fit into the holes.
