I am thinking of using gumstix Overo (tide or water) for a project, where I would need a USB (hub, Ethernet, 6 analog I/O’s and a clock). Unfortunately I could not find any expansion board with these interfaces. I was wondering if it is possible to stack expansion cards. Knowing the interface which I need, which expansion cards would you recommend.
