즉, 아두이노 윤에는 리눅스를 업로드하여 운영체제 가질 수 있다는 장점이 있는데, 아두이노 우노, 레오나르도, 듀에밀라노브, 메가 등의 보드 위에 적층하여 그 기능을 확장하게 됩니다.
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 Shield + 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.
