G120 Board Layout & Routing

In the recommended footprint PDF file there’s a note that states “We recommend no traces or vias under the module.” Is there a specific reason for this? I noticed in the Cobra II preliminary images there significant traces and vias under the module (http://www.tinyclr.com/forum/topic?id=9048&page=1). Any thoughts? Thanks in advance for your help.

@ brice_chart - Welcome.

I believe the latest answer is it’s ok to route under, just mask all vias

Okay, that works for me. I wonder what they are trying to prevent from not having the traces/vias. The EMX module didn’t have that note.
