Hi all,

This one was quite fun to make :)

Please review the pin types. Since this one is used for power, maybe having outputs as power out won't be such a bad idea.

Nice ! :) It's in SVN.

Two suggestions for improvements:

- label also pin 2 with D2

- maybe put pin 2 on top, 3 below

- if I understand things correctly, confusingly named ON/OFF is
  really ON/nOFF, so you could add the "n". Since the label is
  text, we could also use an overbar (i.e., ON/~nOFF), but we'd
  lose it again when/if we can express out-of-the-way pin names
  directly in KiCad.

And the input as Power In. Yes, why not. This seems to be indeed
mainly a power switch, not only in our use.

I've now updated the expanded view as well. I have yet to review
them properly. I'm also trying to get you checking access.

Thanks,
- Werner

I did not because original drawing in GTA02 and in datasheet only label the uppermost pin. :) Which is understandable, because it's redundant information. It's
mainly there for power purposes.

Again for the same reason. I also did not like to name it that way. I do think "ON" would suffice though. :) Otherwise we'll start to change "EN[able]" pins to
"EN[able]/nDIS[able]" :) Some manufacturers seem to label pins in a very weird way - why the heck they name "S2" the input anyway? I got so confused that I had
to read datasheet three times so to be sure I was not missing anything.

Yes. I'll update. That will make DRC happy.

Yeah, it's redundant and one can actually see that it is. Still,
I think it's better to name all pins. Otherwise, someone might
think the name was simply forgotten. (And equivalent pins don't
always have the same name, e.g., VSYS1 and VSYS2 on the PMU.)

> Again for the same reason. I also did not like to name it that way.

Yeah, very good point. Let's keep it simple.

I wonder how they ended up with something as absurd as ON/OFF.
Almost seems as if they moved it from document processing system
to another and lost an overbar in the transition.

> Some manufacturers seem to label pins in a very weird way -

Oh yes, they do ...

> why the heck they name "S2" the input anyway?

"Source of FET #2" ? ;-)

> Yes. I'll update. That will make DRC happy.

Thanks !

I could accept that if we had "Source of FET #1" :)

Updated version in attach. I also changed "R2" and "R6" pins to passive, "S2" to power in and both "D2" to power out.

Why make it obvious if you can create a work of art whose true
meaning will be hotly debated for years ?

Wonderful, thanks a lot !

The spacing of the component name doesn't look too good in
http://people.openmoko.org/werner/gta02-core/gta02-core-expanded-all.ps.gz
but that's only because of my script that prepends an X.

By the way, if you use IRC, you may want to join the channel
#gta02-core on irc.freenode.net. It's usually quicker to
discuss small issues there than by mail.
