Is it possible to connect the XBee to the Arduino without a shield? Currently most of the sources that I have looked at have some sort of shield connected.
I use this shield currently: http://www.adafruit.com/products/126.
From the looks of it, the shield only ensures that the power levels are regulated to 3.3v from the 5v output that the Arduino gives. Can I then just build a small regulator circuit rather than purchase the entire shield for $10 + shipping?
