Hi, I purchased an Arduino ADK R3 and was going thru all the pin-out and IC. On the Hardware page of Arduino website it is mentioned that the ADK comes with either 8u2 or 16u2 IC. As far as I know, this IC is used for data communication between the board and USB.
I would mainly like to know what are the differences between the 16u2 IC ad the 8u2 IC. Also what are the other uses of it on this board??
Thankx in Advance :)
