Hi, I tried to use the minimum connections of XBee micro module as the data sheet specify: VCC,GND,DOUT,DIN,RTS,DTR and also I connected the capacitor as near as I could to the voltage but the X-CTU software doesn’t recognise de module (I connected my own board to the sparkfun explorer USB). Any idea about the minimum circuit that I need to use the module.

The minimum lines need for the radio to power up and two way communications to work is VCC, GND, DI and DO.
