Config for : Xbee with Arduino Nano

Hello,

I have the project to use two Xbee modules to get a wireless connection. I am not sure about the devices I have to buy for that. Could you please advice me?
I think I have to get :

  • 2 Xbee modules
  • 1 XBee Exlorer USB
  • 1 Arduino

Actually, I have already a Arduino Nano, am I required to buy this kind of add-on : XBee add-on for Arduino Nano ?
Is it no smaller?

Thank you :slight_smile:
