Dragino Yun Shield is one of the most powerful shields for Arduino Board. Dragino Yun Shield is designed to solve the Internet connectivity and storage issue for Arduino Board.
Dragino Yun Shield runs Open Source OpenWrt system (Same system as runs in Arduino Yun) and it is fully compatible with Arduino IDE v1.5.4 or later. Dragino Yun Shield is the ideally choice for Arduino Projects which require various internet connections and more storage.
Basically, Dragino Yun Shield + Leonardo equally to the official Arduino Yun, but Dragino Yun Shield is more flexible because it can work with other Arduino board such as Uno, Duemilanove, Mega etc. And Dragino Yun Shield uses external wifi antenna which provides stability and possibility for various environments.
