Even if the K1 is forced to be a top-shield, it is interesting to mount stackable headers (with female holes on top) so there is no need to solder the extra rows of headers to have easy access to other GPIOs.
Prototyping zone must be removed.
Note that if we are removing the prototyping zone, then the second row of pins in the Arduino header is not needed either.
