This is an cheap arduino mockup. There are parts where materials are not yet inserted, such as capacitors, so please change them freely.
The completed version is released here https://www.blendswap.com/blends/view/91290
The model I made as a reference is http://goo.gl/cp1Gon
The base notation of input / output pins is fictitious.
The main thing in arduino - the overall dimensions, mounting holes, number, location and name of pins. Your work looks very good, but without the above, it has no practical application, unfortunately.
I was convinced of what you were saying. I have released a newly completed Arduino design file.
Please have a look, if very well. https://www.blendswap.com/blends/view/91290
Is that a fantastic version of Arduino?
