LVDS
The MB-SMARC-3 provides an LVDS interface for direct connection of suitable displays. This functionality is only available when
the connected SMARC module provides LVDS and the multiplexer on the mainboard is switched to LVDS interface (DIP switch S2
is “OFF”).
Please contact
for further information about eDP or LVDS support.
There is also a connector on the carrier board to power the display backlight (for further information see next page).
The MB-SMARC-3 has an on-board EDID EEPROM to store display specific timing information. This EEPROM can be programmed
with an external I

C programmer. If the programmer supports 3.3 V output voltage, the MB-SMARC-3 can be programmed
without any additional power supply. In this case no SMARC module should be connected to the carrier board.
