Tip: This is the only portion of the link that's required (everything up to the "?")

But even better as a direct link

A quick search suggests that the OT3239 is the same as:

But that was Google. I know very little about these interfaces.

I9341 is one of the main "bread and butter" displays for the Pico. That's the "reference" display if you like. It has some disadvantages over some of the newer displays, but it does most things ok. I prefer the 3.2 inch version personally.

Incidentally, when you post a link you only need the part before the ? character. The rest is tracking information and stuff.

You can put a link into a post using the Link button (the one with a chain link over a globe). You are prompted for the text that you want others to see then for the actual HTML link itself. All you see in your post when it's uploaded is the text.

The OPs original question is about touch compatibility. In that link it doesn't say which touch chip is used but in the photo it looks like the standard resistive foil and chip.

The PicoMite supports XPT2046 resistive and FT6336 capacitive touch chips.
Resistive is the default and OPTION TOUCH FT6336 for capacitive.

What about this one?

A little more expensive.

EDIT: WIKI See mmbasic manual: The Waveshare should not MISO have issues.

OPTION LCDPANEL ILI9488, OR, DC, RESET, CS [,BL] [,INVERT]
Initialises a TFT display using the ILI9488 controller. This supports 480 * 320 resolution. Note that this
controller has an issue with the MISO pin which interferes with the touch controller. For this display to work the
MISO pin must not be connected.

OPTION LCDPANEL ILI9488W, OR, DC, RESET, CS [,BL] [,INVERT]
Initialises a TFT display using the ILI9488 controller. This supports the Waveshare 3.5" display as used on their
Pico Eval board and the normal 3.5" display adapter.
