With the Design now released, I decided to print out a 1:1 scale copy of the board on card stock, just to see that: yes, it is indeed the exact size of a credit card (or any card that fits in your wallet).
I Inverted it to look good on paper, and rotated the hue to match the Raspberry Pi logo. On the reverse side, I placed a QR code (I have not tested it, but it should point to raspberrypi.org) and the logo with the name (in Lucida Handwriting, because I do not know of an official font) and the tagline and URL beneath.
Man, This thing is Tiny!
Take a look:
Here it is with a stacked USB port and a cat5 connector I had laying around:
Feel free to contact me if you want the PSD.
Now to have a copper clad version with all the parts installed...
Edit: You can get the PSD file here:
Note that it is not at 300dpi (it\'s an odd 257.388dpi), so it\'s not the best for printing, but that way I didn\'t have to resample the circuit.
