geeetech linux、wifi、イーサネット、usb、arduino leonardo向けオールインワンyun shield、国連、mega2560、duemilanove開発ボード chjx linux, wifi, ethernet, usb, all-in-one yun shield compatible with arduino leonardo, uno, mega2560, duemilanove iduino_yun_shield, an extremely powerful development for arduino board, is designed to solve the problems of connection and storage which exist in the ar duino board. iduino_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 versions. yun shield is an ideal choice for arduino projects which require various internet connections and more storage.<br>actually, iduino_yun_shield is equal to the official ar duino yun, but iduino_yun_shield is more flexible because it can work with other ar duino board such as uno, duemilanove, and mega etc. iduino_yun_shield uses external antenna which provides stable connection under various environments.<br>the iduino yun is the core module of iduino_yun_shield. and it requires 200ma current when in full load, so it is powered by the arduino vin pins to avoid overheated in the arduino onboard 5v ld0.<br>
