ESP32-Cheap-Yellow-Display

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.

Features

The CYD has the following features:

ESP32 (With Wifi and Bluetooth)
320 x 240 LCD Display (2.8")
Touch Screen (Resistive)
USB for powering and programming
SD Card Slot, LED and some additional pins broken out

Who is it good for?

I think it's useful for the following types of people:

People just getting started with working hardware - as everything is already connected, there is no soldering or additional components required
People who are familiar with working with hardware, but are lazy - (like me) Sometimes you just want to build a project without having to assemble any hardware
People who aren't really looking to learn anything, but just want to build some cool things - More about this later.

What is the purpose of this page?

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 Trinty 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.

How do I know if a display is a CYD?

Where to buy?

Buy from wherever works out cheapest for you:

Makerfabs - Seems to come with a 16GB SD card. Makerfabs also stock my ESP32 Trinity (NOTE there will be import due in the EU from makerfabs)

The Basics

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.

Alternative Display Libraries

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.
