i thought about it, but it's really for a completely different application. we want people to be putting these inside projects and soldering directly to their parts, hence the screw holes on a square 2"x2" pattern and the array of 12V power out pairs. the -duino part is just so people will recognize how easy it will be to use. cheers Dec 20, 2013 11:02:46 PM, drorex(a)gmail.com wrote: If you're gonna use the "*duino" name format, might I suggest making it fit Arduino shields? Almost done w/ PCB design.  That's an ATMega328p processor and a ULN2003 for power output up to 3.5 amps out of the box.  Still need to add some connectors for I2C and 12V, 5V.  I usually use SAE connectors http://www.vetco.net/catalog/images/G-QD-10-2.jpg for my 12V loads but we could solder on a barrel jack, or just ship it with holes for DIY soldering of connectors.  Suggestions?
