Re: [Gumstix-users] Connector orientation

[Daniel S. <de...@pm...>]

Hi 'mark,

Thanks for your help. I don't know what the philosophy of the whole 
Gumstix thing is (other than let the users groups be the tech 
support) but I guess it keeps it cheap. I had a fear that some board 
combos might not work. Thank goodness for all of you folks who help 
out, especially those that go to the trouble of posting photos and 
such (e.g. Dave). Above and beyond...
