Program a Linkit Smart 7688 Duo with Arduino IDE

Get the board manager:

To get the board manager we must go to File > Preferences then, in the "Additional Boards Manager URLs" paste

http://download.labs.mediatek.com/package_mtk_linkit_smart_7688_index.json

Then, install it by going to Tools > Board > Boards Manager... You can find it by scrolling down, or just typing linkit in the search box.

As you can see I have already installed it, but if you haven't make sure you do.

Now all we have to do is select it in Tools > Board, and in Tools > Port. As seen here.

Now you can get coding!
