I've run into some confusion about mounting my I/O board, maybe someone could clear this up for me? On my DE10, the female extension headers are almost as long as the mounting spacers in the corners (14 mm); so if I solder in a male header for P7 on the I/O board, its isolation adds 2-3 mm, which makes the I/O board hover above the spacers and sit at a slanted angle when I put the other side all the way in. Yet in pictures it looks like everyone's I/O board is neatly flush with the spacers on the DE10, and properly locked down with screws (and I guess this would be a requirement to make the whole thing fit into the cases, as well). How do you do that? Where does the isolation of P7 go?
On a related note, P7 is only connected to the USB(ish) extension port, right? So as a workaround, could I leave it out for the time being?
