Where ever possible reference designators were left to match LEAP, especially on the XCVR

circuits. Camelot is a strip down version of LEAP with a qerty keyboard. The flip design intent

is to be repairable. Although the XCVR and controller are separate boards, they are

manufactured at the vendor and in all stages of manufacturing, together. The factory does not

at this time have provisions of dealing with them separately. Therefore there is a single part

number that represents both boards. This for the time being means they are stocked together

and you can not order one separately. Effort will be on going to make this not necessary, but

in the interest of ramping as quickly as possible, this was the fastest solution the camelot

team could find.
