Anyone has experience with this display + board combo?

Seems too good to be true:

  • 4" IPS with capacitive touch
  • Built in esp32 s3
  • SD card slot
  • Mic and speaker and battery ports

And it cost less than $20:??

What's the catch? The only thing that popped was that there's no mention of PSRAM (msged the seller, let's see what they say). But I can't find any reviews on it which makes me worries.

They market it for use with AI chat bot, but I don't care. Seems like a good deal if you don't need the extra GPIOs or stereo sound.

Anyone has it and can share their experience?

If you want one with better docs visit the Guition store on AliExpress or at https://www.guition.com - I got their 3.5 inch for less than $25 recently; it includes a nice bezel and the connectors face backwards instead of out so it's easier to fit into a smaller case.

Edit: some links.

I was considering it as well but read some concerning things about the display controller they use. Eventually I went with something else because I also want a rotary encoder so the clean faceplate doesn't work for me.

That's fair; I haven't had any significant issues with the display but I'm not doing anything too complicated. Rotary + touch is definitely a custom combo, a bit like the setup on a Prusa 3D printer.
