Randy, these interfaces are built-in for i.MX CPU. Unless we choose 
another CPU, they will always be there. In their module all these 
interfaces are connected to two expansion headers, if we don't need 
them, we will not connect anything to corresponding pins in the carrier 
baseboard.

Yes, they do offer a development baseboard with all the "household" 
interfaces. My idea is to use their module with our own custom baseboard 
with only those interfaces that we need (Ethernet and USB probably).

They offer PCB design source on their website, we can modify it to 
expose EIM interface instead of interfaces what we don't need. Maybe we 
can even ask them to do it for a fee.
