1.3 Minimum Requirements to Operate the Display
Adapters
1.3.1 PDI Power Supply Connector
Operation of the display adapters only requires supply of two input
voltages (+3.3V with a 1A load and +5V with a 2A load) and the
corresponding GND connections.
These supply pins are located at the PDI power connector X3:
LCD_3V3: X3
2
LCD_5V: X3 4, 6, 8
Connect all power input pins to your power supply and all GND pins.
Corresponding GND:
X3 1, 3, 5, 7, 9
There are also pins reserved for 12V backlight supply but currently
not used.
Caution:
On a custom board we recommend connecting all ava5V input
pins and at least the matching number of GND pins to the power
supply system.
Please refer to
section 3
for more information.
1.3.2 PDI Data Connector
In order to drive a display at least the LVDS signals, 3V3 logic supply
voltage, the /display_enable signal and GND are needed. If the display
has touch, then you also need to connect the pins for the touch.
