There are three mechanical drawings for the Overo COM boards here:
http://pubs.gumstix.com/boards/COMS/Overo/
 
On my recent order of Overo Water COMs, I received ones that matched the R2173 mechanical drawing.
 
Does anyone know if or when Overo Water COMs will be shipped with mechanical dimensions per the R2277 drawing?
And does anyone know if there's any performance issues with R2173 revision that were fixed with the R2277 revision?
Since J5 moved, I'm wondering if specifically there was any problems with that interface.
 
Thanks
