On the SBC-A80-eNUC board, the Digital Display Interface #1 is reserved for the connection of LCD panels having an
embedded Display Port interface.
For the connection of this kind of displays, on-board there is a VESA
for Display Port interface, type I-PEX p/n 20455-030E-02.
Mating connector: I-PEX p/n 20454-030T.
On this connector, SW_BACK and SW_VDD are the voltage rails that can be used to supply the LCD and related
Backlight Unit.
The LCD software-driven voltage, i.e. signal SW_VDD, can be
regulated to be connected to +3.3V_A or +5V_A by closing (short-
circuiting) breakers BR3 or BR4, respectively (only one breaker at a
time, otherwise there will be a short circuit between the two different
voltages).
Similarly, the backlight software-driven
SW_BACK, can also be regulated to be connected to +5V_A or
+12V_A by closing (short-circuiting) breakers BR1 or BR2, respectively (only one breaker at
a time, otherwise there will be a short circuit between the two different voltages).
Please refer to the figure on the left for an indication of the placement on the PCB of the four
breakers mentioned above (they are located on the bottom side, near connector CN27).
Please take care of closing only one breaker per voltage rail (i.e., BR1 or BR2, BR3 or BR4),
otherwise there will be short circuits between the main power rails of the board.
Upon specific request, the board can be supplied configured with the desired voltages
already set. Please contact your Sales Representative for details about this.
