I regularly have to design the footprint and the symbol(label all the pins) on parts that I use, and the pins have numbered in the 200s, for one part, a few times…
It is very nice of GHI to provide the design files for some of the boards, Chipworks being the only one that they dont, so “Thanks GHI!”
Most component manufacturers cant be bothered to give you a decent datasheet, nevermind a component for Eagle or a complete design.
