LCD daughterboard connectors CN11 and CN14

Two 48-pin male headers CN11 and CN14 are used to connect to LCD glass module
daughterboard MB979. The type of connectors, their mutual orientation, distance and
terminal assignment are kept for a number of ST MCU evaluation boards. This
standardization allows developing daughterboards that can be used in multiple evaluation
kits. The width between CN11 pin1 and CN14 pin1 is 700 mils (17.78 mm).
STM32L476ZGT6 ports routed to these two connectors can be accessed on odd CN11 and
CN14 pins (the row of pin 1), when no daughterboard is plugged in.
Daughterboards plugging into CN11 and CN14 must keep the even terminals of CN11 and
CN14 open.
