[chbot] Chipkit UNO32

Out of curiousity did you use the Chipkit IDE to check the sketch size.?

Also Arduino do have some 3v3 flavour devices, just not in UNO.

Robin
If you want to try a chipkit UNO32, I have one available.
They are also available at Element14 (formally Farnell) with free 
freight (www.element14.co.nz)
