ESP£" 3.5" Display (Cheap Yellow)

[st_4489665]

I ordered this board from AliExpress, specifically touch screen model, but became suspicious when it didn't seem to have touch screen capability.

From the basic research I've done, I believe it should have a chip at U3 if it is genuinely touch screen.

The model number is esp32-3248s035, although I believe that should be followed br "R" or "C" for a touch screen?

Hopefully someone with more experience could confirm please?

Also, is there an image for this specific board denoting that this would be the touch screen chip?

Thanks in advance.

Hi @st_4489665.

@st_4489665

is there an image for this specific board denoting that this would be the touch screen chip?

There is one here for a similar "CYD":

ESP32-2432S028 (Cheap Yellow Display): high-resolution pinout, datasheet,...

Thanks.

I think I'm getting somewhere with this...

Apparently that chip is for a resistive touch screen, but the layout is different for a capacitive touch screen. Depending on which one you have, the libraries and code are different.
