Re: [Paparazzi-devel] No serial communication between PC & XBee?

[Alston Pike]

I'll post a PDF file to my website later this weekend and get the link posted.

As far as power is concerned, I think the XBee modems are 3.3V, but
are 5V tolerant (that is, if I remember correctly).  The cables
included with the PPZUAV kits drive the modems off the 5V bus to keep
radio interference off the 3.3V line shared with the processor.  That
said, according the specs on Digi's website, the XBee Pro only draws
294mA and the LM317 should be good for 1.5A.

Which FTDI cable are you using?
