DSI Display Expansion Connector Interface
A third display option for the Pandaboard ES is to plug an external display module into the DSI
display expansion connector J7. This connector is a 40-pin, 0.8mm pitch connector (Hirose P/N
FX6A-40P-0.8SV91), and is mounted on the back side of the Pandaboard ES PCB. See
Figure 10 below for the orientation/pin numbering of this connector as viewed from the back
side of the PCB.
A block diagram of the Pandaboard ES Display Expansion interface is shown in Figure 11 on page
