Power consumption and EMC

I would like to use a fitlet in text mode exclusively, ethernet input and USB output only. A few more hardware questions:

7) What is the power consumption/voltage?

8) Do ethernet and usb have separate channels?

9) How many layers is the mainboard? Does ground have separate layer?

10) Did you measure emi/rf? How does it compare to Fit-PC2?

Thanks

7) Power consumption is very dependent on workload. 5W is a reasonable assumption.

8) Yes. Please consult block diagram.

9) The PCB is over 8 layers. There are multiple ground layers.

10) EMC testing is underway. fitlet meets CE mark class B and is comparable to fit-PC2 in low radiated emission.

Thanks for your reply. All very interesting.

7) At what voltage/ampere?

7) 12V, ~0.4A
