Hello all,

I bought a LCD Module with a 20 Pin LVDS connector. I would like to connect this display to the cubieboard2 or the baseboard but unfortunately I do not know how to connect the pins:

The LCD Display connector has 20 pins:

1 VDD P Power Voltage for Logic: 3.3V

2 VDD P Power Voltage for Logic: 3.3V

3 U/D I Vertical Reverse Scan Control

4 L/R I Horizontal Reverse Scan Control.

5 IN0- I - LVDS differential data input

6 INO+ I + LVDS differential data input

7 GND P Ground

8 IN1- I - LVDS differential data input

9 IN1+ I + LVDS differential data input

10 GND P Ground

11 IN2- I - LVDS differential data input

12 IN2+ I + LVDS differential data input

13 GND P Ground

14 CLK- I - LVDS differential data input

15 CLK+ I + LVDS differential data input

16 GND P Ground

17 IN3- I - LVDS differential data input

18 IN3+ I + LVDS differential data input

19 VLED P Power supply for backlight: 12V

20 LEDADJ I LED PWM signal

NOTE : Pin20: ADJ is PWM signal input. It is for brightness control.

ITEM SYMBOL MIN TYP MAX UNIT

ADJ signal frequency Fpwm 10 -- 100 KHz

ADJ signal logic level High VIH 3V -- VLED (12V) V

ADJ signal logic level Low VIL 0 -- 0.4 V

The cubieboard2 baseboard pin assignment:

1 VSEL

2 VSEL

3 VSEL

4 GND

5 GND

6 TXO0-

7 TXO0+

8 TXO1-

9 TXO1+

10 TXO2-

11 TXO2+

12 GND

13 GND

14 TXOC-

15 TC0C-

16 TXOC+

17 TXO3-

18 TXO3+

19 TXE0-

20 TXE0+

21 TXE1-

22 TXE1+

23 TXE2-

24 TXE2+

25 GND

26 GND

27 TXEC-

28 TXEC+

29 TXE3-

30 TXE3+

GND is the only pins that are obvious to me. What about the others? Can somebody hep here?

Thank you very much!

I have bought the cubieboard baseboard for 30$ from this website https://store.iotllc.com/product.php?productid=3&cat=0&featured=Y (https://store.iotllc.com/product.php?productid=3&cat=0&featured=Y). It routs all of the pins so that you can plug in the lvds display so long as you have the right cables to do so, which are easy to obtain, they can usually ship them with the screen. It also brings the pins out to have larger spacing, so that if you would still like to learn how to plug a screen in manually, it makes it much easier.

Hope this helps!
