Arduino YÚN Shield
Yún Shield is a powerful IoT shield that allows you to remotely upload sketches to your Arduino board and connect your board to the Internet.
Going online is simple thanks this sketch you can use to configure your shield and to the Yún Web Panel. The same panel allows you to manage your shield preferences and upload your sketch (in .hex format) on the attached Arduino board. The Yún Shield gives you the possibility to use the Bridge library and so extend your board capabilities using the Linux processor exactly how the Yún board does.
