I have been lurking, reading, and googling my eyes out for a little over a week now. I am planning on buying a arduino however in seeing the couple different variants out there was looking into (and attempting to learn) how to build my own board. I see there is a single side serial arduino however I saw a post where someone mentioned to build a Riduino as it was, I believe, a two layer board. Now I can not find anywhere how many layers the Uno has.
I am already getting a parts list together, building a work bench, have a digital soldering iron, I am planning on building a UV exposure box as that seems to be one of the best/easiest was to begin creating PCBs, blah, blah, blah.
I would prefer a Usb board versus serial that I could build here at home. Any suggestions? Thanks for any input, advice, nudge, or kick in the right direction.
