Hi guys.

i am going to use the 3.5inch HDMI screen from KeDei on my next build.

there is a backlight switch on the control board.

I was wondering, is it possible to remove that, and add a pot (like the original contrast wheel) to make the backlicht (brightness) variable?

any thoughts?

I am not that good with resistors and calculations on that... so no idea if and how this can be done
