Since COM Express modules can offer eDP or LVDS interface on the same pins, these require a proper
high-speed differential pair switch, which will make available LVDS interface on connector CN34 or eDP
interface on connector CN33. Selectin between these two interfaces can be don by using Jumper
JP10.
