The UNO's zig-zag shape

Anyone know why the Uno has the zig-zag shape on the right hand end, and isn’t cut square?

Or to make the shape unique and, therefore, harder to copy.

It was inherited from the Duemillanove. I'll guess that it was a realization once most of the board design was complete that there wasn't enough room for the ICSP connector without that little extension.

Well, if that were the idea, they sure messed up by providing all the source files. :wink:

I'm going to guess that it was done to make it easier to break the multiple boards off the panelized board. Original Dues appear to have had scored edges (judging by the Duemilanove picture on Wikipedia).

From the horse's mouth... http://forum.arduino.cc/index.php/topic,2022.0.html

I remember a post from David C in which he describes designing the shape. What I remember is that it fits comfortably in the hand when connecting the USB cable or shields.

Like I said, Just somebody trying to be artistic, there can be no technical reason for doing this, at least none I can think of.
