New Gear Best Screen Layout

Post by tayman208 » Wed Jan 18, 2017 8:05 am

Hey everyone. I'm super new to this so bear with me.

I recently ordered a 3.5" screen from gearbest just like the one the wiki shows. However, the one I got has a slightly different layout on the board that the one pictured on the wiki.

As I do not want to fry my board, would anyone be able to show me where I should solder to make this one run off of 5v? Thanks a million. This forum is the best.

The board layout looks slightly different to all the images I have but more than likely the same chip used so you can just compare. No guarantees as I got this off the web whilst doing research for my own project. Good luck.

Hi, I got the same one you have. Basically I'm doing the same short as everyone else in the other versions, but I've followed the trace from the output pin on the voltage converter chip to a more solder-friendly location.

Haven't soldered it yet, but it worked on the bench when I supplied 5V to the pad - standard disclaimer, etc.

Enjoy!

Can I use any wire to solder this modification? Like a piece of the red wire from the lcd board?

Thanks for the help! I did the mod (I think) and the screen powers on and runs well. However, the small text is blurry and almost unreadable. Anyone have any thoughts?

Also, are you soldering to the arm of that piece as shown in the diagram? or the pad to the right of it? I cant tell by your picture which you soldered it to. Is that what you were referring to by the "more solder friendly spot"?

Thanks again for the help. I love this forum.
