Hi all,

I'm new around these here parts, but I had a quick (probably stupid) question.

I'm looking into creating a device with the Tobi-Duo dual-ethernet expansion board.  My understanding is that in order to do anything with this I also need a COM module which mates with the expansion board via the two 70-pin connectors.

My question is that both the COM module (say the plain ol' Overo Earth) and the Tobi-Duo have +5V barrel connectors.

Does that mean I need two power supplies for my device?  Or is the expansion board powered by the COM module via the two connectors?
