The version number should be V2.0 or superior, as the changes from V1.0 justifies the new version number
what PCB design software do you use to make those nice looking 3D images of the board
I think I will also add the 3.3V regulator

QuoteI think I will also add the 3.3V regulatorI used a 78L33, simply because I have them in inventory. Sadly there doesn't seem to be a standard for 3.3V regulators, the 78L33 is only made by ST. Other manufacturers make other regulators, and you may find a better choice for you; I found most to be pricier and require larger stabilizing caps. A different regulator may have a low enough drop out to run from the 5V rail though instead of Vin.
