What's the difference between Arduino Wi-Fi Shield 101 and Yún?

Official Hardware Classic Yún

What will be the pros & cons of Yún compared to Arduino Wi-Fi Shield 101?
Will the IDE 1.5.7 support both and will be the Bridge part of programming Arduino Wi-Fi Shield 101?

The major difference is that on the Yun, the WiFi part is controlled by the Linux par of the board while the WiFi shield is controlled by the AVR part. Totally different way/approaches necessary to work with either one...

Thanks, that matches exactly what I understood out of the new 101 specs.
But do the libs for SD and Wi-Fi access plus my own code all fit in the Unos memory?

No, of course not.
As mentioned, the WiFi (as well as the SD) are only accessible from the Linux side of the Yun, they are not accessible on the AVR side, hence any such library (even if Leonardo compatible, as that is the basic Arduino board the Yun is based on) will NOT work...

With the Yun, you have to realize that you need to work with a different concept, with two processors/environments that work independently/concurrently.
Some resources are only available/accessible on the Linux (MIPS AR9931) side, like WiFi, Ethernet and SD slot, while others are exclusive to the AVR side (I/O pins).
And for communication between those two concurrent parts, you have to use the "bridge".

Think you miss interpreted my post.
I'm already familiar with the Yun. I was referring to the new Wifi shield and if all the libs to program this will fit in the UNOs memory.

Well, in that case, you should post your question in the Uno forum, and not in the Yun forum... :wink:
