Surprisingly didn't find an answer in FAQ: Why the Arduino form factor is so strange? Is there any reason
to be not strictly rectangular?

Thanks for explanation, if there exists one...

Good point wiz, I've updated the .sch file.

If you are interested for another Arduino board clone
compatible with the Parallax Boe-Bot robot, completely
designed using the gEDA tools, please visit my page

It is not so easy with the Scott Edwards LCD Serial Backpack. The input signal is inverted (that is more complicated than just sending ~char instead of char) so you have to:

a) use an hardware inverter, or

b) use a NewSoftSerial library which enables to invert signals.

Moreover, the LCD is quite sensitive to precise timing and good initialization.

My working example can be found here:
