Which ESP32 Do I Purchase

I just found out (The Hard Way :unamused:) that neither an ESP32 or an ESP WROOM will drive an ili9488 4" display. Apparently neither of these devices has sufficient psram and the only way to drive the display is with an ESP32 WROVER. I’ve been looking for a suitable device. I looked on Amazon but there only seem to be kits that include a camera. Spec’s are lacking and it’s hard to tell if this would work sans the camera?

I also found an ESP32-S2-Saola-1R at Mouser Electronics. I’m not sure if this is what I need, but it seems to be correct.

Would someone mind telling me if any of the above would work or where I can purchase an ESP32 WROVER (with wifi) that can be delivered in a couple of days.

Much appreciated

Have a look at the ESP32 DEVKIT ads (unfortunately on Aliexpress - so no quick delivery). Some of these have WROVER variants you can choose. I bought a few a couple of months ago. Work fine with a larger display, up to 320x240.

EDIT: Be careful buying a camera variant - access to a lot of the ESP32 pins may be tied up in the camera connection.

This looks fine…
