I have to connect my Xbee module to my Arduino standalone board and I'd like to know if i have to convert Rx and Tx arduino level to 3.3V if it is not necessary.
I've already bought from sparkfun some modules like these: http://www.sparkfun.com/products/8745 but then I've seen on "Building wireless sensor network with ZigBee" that arduino and xbee can be connect even without the logic level conversion since on the book there is xbee module directly connected to 3.3V for the Vcc pin and Rx and Tx pins are connected to the Arduino ones without the presence of any logic converter or voltage divider.
So, I would like to ask you if I can connect the xbee module without using any level conversion and by only connecting xbee Vcc to 3.3V.
