Wiring up ili9341 screen

Post by Doc105 » Sun Apr 28, 2019 12:57 pm

I was wondering if I want to use an ili9341 screen on the pi without the original controller board, do I have to use any resistors or other components, I’m curious because I’ve seen it done both ways.

You'll need one 3r9 resistor if you dont use the ones with a board, alongside some sort of breakout of osh

This is really helpful, did you design that pcb? if so would you mind sending me the eagle files? Having an example would be super helpful.

If you follow this:viewtopic.php?t=2312 and use 18pin screen, the scheme will be as follows:

Not 10 ohms use 3.6ohm or 3.9ohms to have the proper backlight, using 10 ohms will slightly dim the backlight unless you want it that way.

Don't contact me about obtaining my board files (as you will not get them). If my Boards or PCB Kits are sold out, they will be restocked as soon as I can get them and there is demand for them. You can join the mailing list on my Website to be notified when they are available.
