The potentiometer that comes with the driver board is a "snap-in" mount, intended to be soldered into a board. There is no easy way to mount the snap-in potentiometer in the case. The optional potentiometer is a board-mount with a nut and washer and is appropriate for mounting in the case.
As such, you might want to remove the "Optional" from the optional potentiometer and just make it the default?
