It is not only staggered on each line of header holes, but IT IS ALSO offset of the center point of the top and bottom lines by 5 mil. This causes the headers to lock into place on the standard footprint on the LCD screen. The extra squares on the tdocu layer are there simply to reference other pins (if you were to actually populate a longer header than ten long - this is what we do with the backpacks).M10X2M10X22X10_LOCK_SPECIALSPECIAL2x10_lock_specialsparkfun Pin Headerspecial1101112131415161718192203456789
