i am thinking about buying a gumstix Overo with a Tobi Expansion board.

But my Problem is, that I can´t really find information about the Resolution + Sampling Frequencies of the PWM and the A/D Lines, which are routed to the 40 pin header.

In the tps65950-Datasheet it says 16 bit PWM and 15 bit A/D Resolution. In the "Overo Design Overview" the A/D line is labeld whith 10 bit.

So i am a bit confused and it would be pretty cool if cou could give me some reliable Information about the Resolution and the Sampling Frequencies.

Is there a Port on the 40 Pin Header to use an external Clock ?


Thanks so far,
