Hey all,<br>
<br>
Well here it is, the last version which was even harder then the 3rd
one. or so it seemed anyhow.<br>
<br>
I will work on copying these four to the bottom and renaming the
labels before sending them off. I'll post the final pcb on this list
again,but routing wise, Nothing will change, unless of course
someone found a grand mistake.<br>
<br>
So really, all input is greatly appreciated :D would be shameful to
send this off to get printed, just to find bugs and have another
batch made.<br>

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