3.5.7 LVDS
The MB-COME6-4 provides a LVDS interface where suitable displays can be directly connected.
To select the LVDS interface on the MB-COME6-4 the DIP switch on the carrier has to be set to the “LVDS” position.
This functionality is only available if the COM Express™ module provides the LVDS interface.
There are also connectors to power the backlight of the connected display.
The MB-COME6-4 has an on board EDID EEPROM to store display specific timing information. The EEPROM can be programmed
with an external I 2 C programmer. If the programmer supports 3.3 V output voltage, the MB-COME6-4 can be programmed
without any additional power supply. In this case no COM Express™ module should be connected to the carrier board.
