Arduino now has 3.3V
My friend and colleague Tim McNerney pointed this out to me the other day. I just bought the Arduino Duemilanove, and now you don't have to worry about toggling the jumper, and it has 3.3 and 5 Volts. With the other Arduino, I always had to scour around for a 3.3 voltage regulator, but now I won't have to with Arduino Duemilanove.
There's also a cool print of Italy on the back of it. I think it is approximately $30-$35 still.
