There is an ESP32 with a built in 320 x 240 2.8" LCD display with a touch screen called the "ESP32-2432S028R", since this doesn't roll of the tongue, I propose it should be renamed the "Cheap Yellow Display" or CYD for short. This display is only about $15 delivered so I think it's really good value.
The CYD has the following features:
I think it's useful for the following types of people:
So this is pretty nice hardware and a cheap price, but the software instructions/support around it is pretty poor. Just a single link to a zip file on a random website.
A couple of years ago I released the ESP32 Trinity, which is an open source ESP32 board for controlling Matrix panels. I think the main benefit people get out of the work I did on the Trinity is not the hardware, but the documentation, example code and ready to go projects.
I'm no longer creating hardware products, but I think it would be interesting if we could create the same kind of community around this display, where people can share examples and projects made for this display.

For details on how to get started with your CYD, please check out the Setup and Configuration page
A collection of examples demonstrating how to use the different features of the CYD, this is a good place to get started. Check them out here.
The basics examples are based on the TFT_eSPI display library, but the CYD also works with other display libraries too. Here is some example code if you prefer to use an alternative Arduino library. Check them out here.
Some examples for using the CYD in ESPHome. Check them out here.

Some examples of 3D printed stands and cases. Check them out here.
This page contains information about what pins are used where, and what ones are free to use.
This page contains information about additional hardware add-ons that can add functionality to your CYD
This page contains information about how to troubleshoot your CYD device
This page contains information about some hardware mods that can be performed on the CYD to improve or change some of its functionality
This page lists any times the CYD project was mentioned somewhere!

The one exception to this is the OriginalDocumentation folder, that I do not have the right to license
Some members of the community have ported some of this information to other languages!
Please note: I can't gaurantee the accuracy of the translation, how up to date they are or the content on them in general.
If you would like to contribure a translation, please name the repo with the language name or code in the repo name and you can link it here.
