I mean add 3.3V, so you can use part with that voltage easily (original Arduino takes 5V and 3.3V from FTDI chip). I don't know what option is the best, maybe Vasile's suggestion about a "3.3V LDO as BA033 from Rohm" is nice. I'll let you decide ;) > > > > > - last point, and the most important IMO, increase the space between > upper > > and bottom shield connectors.

I'm afraid I won't be able to build a new one this WE, no laser printer, and, worst, no more copper board... Thanks for this !
