on the same side as the ICs, individual caps work better since it allows for a more even

distribution around the ICs.

The CM-2 module was designed using a 6-layer PCB and 6-mil traces. This is due to the

amount of circuitry packed into the small PCB. If the PCB were larger, or the second

Ethernet connector removed, a 4-layer PCB would have been adequate. However, we do

not recommend using a 2-layer PCB.
