Schematics for RasPi are released!

Great news, thanks for posting!

Awesome, thanks for posting.

Sweeeeeeet !

nice.

btw, it looks like capacitors c2 and c3 should be solidly connected on both ends,

not just the +5v end, on page 1, area C3.

Super!  Many thanks to Pete for making them!  Now for some bedtime circuit analysis ...

@jbeale: you've run your two URLs together into one.  They should be:

and

       http://www.raspberrypi.org/archives/1090 .

Sorry for the malformed URLs,  I must have been in a hurry. (Interestingly, clicking that mess actually gives you a helpful RasPi error page which at the moment has, as the first link under "Recent Posts", the very schematics!)

Well spotted coder27. C2 is drawn correctly since it's not a T junction, but C3 pin 2 is missing the dot, and that could be an open circuit.

On a photo of the beta board, you can see at the lower left-hand corner here:  http://www.riscosopen.org/images/rpi/rpi.jpg

that C3 is connected on both ends; at least there are vias on each side.  I haven't seen a clear enough picture of the final board to tell, but from this one it looks the same. http://itlounge.eu/wp-content/uploads/2012/02/1ba94__Raspberry_Pi.jpg

Yes, C3 is definitely connected to something on both ends.  Some schematic editors usually do the right thing creating junction dots automatically, but not always, and allow the user to create and/or delete them automatically.

   This is why when I do a schematic I always print out a textual netlist (PADS PCB format is nice) and manually make sure it agrees.  I usually find something, e.g., a locally-named net that should be global or two net names with similar names that should be identical.  You have to be particularly careful with ICs that have multiple grounds where the software may have only connected one of them automatically.

   I believe the RasPi people went through this sort of exercise which helps explain why beta boards had only one problem IIRC.

Hi guys - I got very curious about this as I know it's connected - what you cannot see is that our very expensive and generally spot on system has actually joined then both on the dot under C3, so that trace between C6 and C3 is actually a double trace!

This is a 'bug' that creeps out when you try to be over neat on schematics and just do 'tidy-up' things.  Interestingly, if you actually do this for real (fail to connect the end of a trace) it leaves a great big red cross at that point and moans and complains when you run a design check.

At the magnification that I was actually looking at the schematics to see what coder was talking about, my PDF viewer shows the double line between C3 and C6 slightly darker than the one between C3 and C2, so I immediately saw what you say too: they are connected at the dot below C6.
