I've worked on a rotated version and planning to do two other orientations as well, so early feedback is good, so I don't have to redo them again :)
Silk screening isn't 100% right, since I still need to rename them eventually somehow (edit .pcb file directly is probably the easiest way?)

Here's my second attempt at routing the previously mailed png of my schema.
It was a lot trickier to route then my previous version, but I think it worked out!
As mentioned, S1 and S2 need to be shorted if U3 is to be omitted. RN1 should be 10k or ideally 100k, as Peter mentioned earlier.
Hopefully there's no obvious mistakes and can start working on alternative layouts (so it is insert-able in different angles).
DRC Check fails on S1, S2 and U3. It thinks the distance is to shallow. That said, DRC check passes when I set the copper width/distance to 7mil's instead of the current 8 mils.
I'm planning on having these PCB's manufactured by Seeed studio and their minimal width is much smaller.
Minimum trace width: 6mil Minimum trace/vias/pads space : 6mil Minimum silkscreen width : 4mil Minimum silkscreen text size : 32mil
I've used a grid size of 10mil and distances of 8 mils, as I didn't want to rely on the minimum of seed. The silkscreen I positioned using a grid size of 5 mil's however. Not sure what they mean with a 'minimum silkscreen text size' however.
Anyhow, feedback greatly appreciated, so I can start working on alternative layouts :)
