13.4 DSI_V3 display board connector (CN2)
The 64-pin connector (CN2) supports DSI_V3 display add-on boards.
Pin 61 to 64 (central pads for ground reference) are not accessible when an add-on board is plugged in.
The MB1829 on-board connector reference is QSH-030-01-F-D-A from SAMTEC. The MB1835 on-board mating
connector is QTH-030-02-F-D-A (for a total height of 8 mm between boards).
