From the latest product, Yun, Arduino REFUSES providing EAGLE files (including hardware PCB,CAD files and the placement files) on the official website.
Arduino seems to try to become a company selling hardware all for profit.

The promises NO more extends:
"The boards can be built by hand or purchased preassembled; the software can be downloaded for free. The hardware reference designs (CAD files) are available under an open-source license, you are free to adapt them to your needs."

If anyone thinks they can build their own Yun from scratch must be seriously out of their mind...

Just my 2c,

The complexity of a device like the Yun is simply beyond what you can "do it yourself". All learning aside, I could just not see me wasting any time on even trying to source all the parts let alone trying to solder this together, considering that these are mostly SMT parts...

What's under the silver cover?

Well, complexity for some~~~,  for others, it's an opportunity to move forward.
I was just curious about what was under the silver cover.
After carefully cutting the two soldering points and taking away the cover, everything just works fine.
No, not fine, it's even better. The average signal strength rises from 52% to 63%.
I really need the answer why arduino wants to hide the information of Yun and change their promised attitude, "opensource".
They use cover, refuse to put the EAGLE(brd or .sch) files in public, and not even release the AR9331 mapping.

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.
And it is well known what is under the cover, every schematic of the Yun will show that it is the Atheros 9331 and related components.
I for one am interested in using the Yun, not building one. And all that information is readily available...

Then why the official WIFI shield has no such cover?

Oh, really?    Then     show    me!   Ralf~

These are all we can get from the internet:
http://arduino.cc/en/uploads/Main/arduino-Yun-schematic.pdf     (so called an incomplete schematic)
http://www.dragino.com/downloads/index.php?dir=motherboards/ms14/  (reverse engineering by a Chinese company)
http://linino.org/doku.php?id=wiki:hardware  
http://linino.org/lib/exe/fetch.php?media=wiki:dogstick-04-linino-a.pdf
(incomplete schematic again if you do see the photo showing what is under the cover)

So?    Show     me      what you called the "related components" with a specific link and a page number.
Where is the Atheros 9331 Mapping and where are the .brd or .sch files which can be "adapted" ?

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

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

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

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

Show me. The "schematic" of your "well known",  "related components under the cover" with a specific link and a page number.

This is a honesty issue of Arduino and their team.

Jming is not wrong on this, while I would certainly not build one by hand having the schematics available could be handy and more than that you cannot claim arduino to be open-source if there now one which is not just by principles.

Whether you would build one by hand or not is completely irrelevant to the discussion, I have not verified but if the schematics and are not available the Yun is indeed not open-source by definition...
