I would like to print a fairly common circuit. But I don't want to design the PCB myself. Where should I look when searching for PCB layouts?

I think this may fall under community wiki, unless a single answer will probably clearly be correct, I think this will have many people posting different questions. – Kortuk Oct 21 '10 at 0:02

If you're interested in arduino, there is http://shieldlist.org. It's a wiki listing of all of the boards that can interface to the arduino board. All should be licensed as open hardware.

I'm very interested! – Jader Dias Oct 21 '10 at 23:30

Several places publish open-source PCB design files:

Sometimes people post open-source hardware design files on one of the popular open-source software places -- Google code, Sourceforge, Launchpad, Github, etc.

A few places are trying to make it easy to buy open-source PCBs -- the actual, physical things you hold in your hands, not merely some computer file:

opencircuits.com is interesting – Jader Dias Mar 16 '11 at 20:14
+1 for OpenCircuits. – Kevin Vermeer Mar 16 '11 at 22:24

I found some open source hardware at


but there are many software projects in these results also.

The only way I found of getting hardware only results is searching for PCB files:

The file searches won't catch everything, because different EDA packageshave different naming conventions. .pcb .pcbdoc .brd , .grb .gto .057 .gbl .gto .gbo .gts .gbs etc... off the top of my head – Connor Wolf Oct 21 '10 at 5:17
@Fake thanks, I edited the answer to include a link that searches for all those extensions – Jader Dias Oct 21 '10 at 10:34
The list I gave is not comprehensive. It still may miss some results. – Connor Wolf Oct 22 '10 at 7:06

Maybe you find something interesting in the Arduino board at Dangerous Prototypes forum:

Project development, ideas, and suggestions >> Arduino

I would like to add: that's a link to the Project development, ideas, and suggestions for Arduino section in the Dangerousprototypes.com forum. – Jader Dias Oct 22 '10 at 11:35
Added it into the post for you. – Amos Oct 22 '10 at 13:53
Made it better. – OIO Oct 22 '10 at 18:05

http://bildr.org/ aims to be a complete open source electronics community (wiki, forum, etc.)

http://www.opencircuits.com/ aims to be a complete open source electronics wiki

(I found both via SparkFun)
