3. New box design looks smaller.
4. Add internal speaker.
5. Add relay module for  auto on/off LED light with my LCD remote.
6. Batter box finishing look like company product.
7. Add new menus buttons.



How to add relay module?

I bought 5v relay module from ebay.in @ 190 /- INR. I connect it with my 5v lcd controller pan drive power source and output terminal (COM and NO) connected with LED light driver and 240v power source. Now when I on my LCD controller with my remote the relay get triggered and LED light on automatically.
