Great work, thanks a lot !
We discussed a few issues in IRC. Some that are of more general
- how to write values and units: lots of details. See my previous
- the handling of ground is messy in the GPS schematics. Openmoko
have RF_GND and GND, but the two aren't distinguished properly
(e.g., some things run from RF_3V to GND) and are treated as
identical in the layout anyway. Alvaro has a few more ideas
about this which I think he'll elaborate soonish.
- when naming nets, local labels should be used for anything that
connects within the same sheet and doesn't connect on any other
sheet. Local labels are created by naming a "wire". (The button
aboce the global labels.)
- we should reference the ECNs in the schematics. That also gives
us more room for explaining quirks.
There were a few small changes and C7625 is still missing, but
besides that, the GPS looks pretty good.
