Hi all,My Arduino Yún is just arrived. I'm seeking around the 5V wall power adapter for it. Luckily, I found three wall power adapters at home and I hope I do not have to order the other one on line. Option 1: Apple iPad 12W USB power adapter. 5.2V 2.4AOption 2: Apple iPhone 5W USB power adapter. 5V 1AOption 3: Unknown brand 5.0V+-5% 0.15~0.7AThe best choice is probably option 2. Can I try option 1 or option 3?Thanks.
