1 Introduction
1.1 About this quick start guide
This is a quick start guide to introduce what is Yun Shield and how to use Yun Shield with Arduino
Leonardo and run simple Bridge examples. For more detail about Yun Shield system other
features or use with other Arduino boards. Please refer the Yun Shield User Manual.
1.2 What is Yun Shield
Yun Shield is one of the most powerful shields for Arduino Board. Yun Shield is designed to solve
the Internet connectivity and storage issue for Arduino Board.
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. Yun Shield is the ideally choice for Arduino Projects
which require various internet connections and more storage.
Basically, Yun Leonardo equally to the official Arduino Yun, but Yun Shield is more flexible
because it can work with other Arduino board such as Uno, Duemilanove, Mega etc. And Yun
Shield uses external wifi antenna which provides stability and possibility for various
environments.
