After review, a few minor tweaks and additional mounting holes added I have finally submitted the 1Bitsy 1UP PCBs to @oshpark.

I really hope I did not make some major mistakes with the schematic. I have added a PDF export of the schematic to the project page here just in case anyone wants to review it. (if you find something do tell me in our gitter channel, but sadly because I have ordered the boards already I won't be able to do much about it now, besides bodge wires if possible)

I got some really good input from twitter, to add a back plate to the board to provide thickness and a good grip. That was a marvelous idea, so I went ahead and added a few m3 holes for PCB standoffs. I have some standoffs in white nylon but I think I need to get my hands on black ones, unfortunately I don't think they make them in purple unless I get aluminium standoffs that are purple anodized but as far as I remember that purple is usually quite unpleasant. :)

All in all, we have very good progress on the project! Can't wait to get the boards back. I probably should place the order for the massive DigiKey cart that has drown over the course of this project. :D
