Arduino is NO more opensource from Yun

Jming:

PCWorxLA:
As for the cover, it's likely for RF shielding purposes, so the device will pass certain restrictions, like with the FCC here in the USofA.

Then why the official WIFI shield has no such cover?

Maybe because the chip(s) used on the WiFi shield don't emit unwanted RF emissions?

Where is the Atheros 9331 Mapping and where are the .brd or .sch files which can be "adapted" ?

PCWorxLA:
I for one am interested in using the Yun, not building one. And all that information is readily available...

Again, I am interested in using the Yun, I have neither interest nor time even to try and rebuild one myself.

No one will stop you from moving forward except you like sticking around.

Come again? Please try to understand my statement above...
