Ah, that's better: a higher-rez (1328X2645) version of the pic is available
here.
I'm thinking I agree with nekokami's assumption that the board is so huge because it's for prototyping. I can see what looks like a speaker, a couple of 9-pin D serial ports, several switches and micro-buttons, a good sized pot' or two, some rather large caps, a couple of other connections, a piggy-back board -- in short: a bunch of bulky, discrete components that I'd expect to be removed altogether or replaced with more 'integrated' components on any production, um product.
Anyway you
want stuff to be bigger for prototyping, it makes it easier to adjust the design, and repair things when you slag components.
