G200X schematics? was Re: USB ports ?

Hello Mariss,

Congratulations on the G204V "completion". It's sure to be a market
beater...

Re: G200X
Since this has been an open source project from the beginning, I
expect we'll soon be seeing those "spiffed-up" schematics on the
Geckodrive group website?

Thank you in advance,

Ballendo
