Why is pin 9 and pin 35 the same or connected together. Is this an error in the schematic.?
It appears they are but I don’t know why. I’ll ask our engineering team to see if the files are out of date.
OK, it looks like that was intentional, apparently so that you could use the board for things like HDMI? I think there wasn’t enough room to break both out so we connected them on the board.
