# 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](https://github.com/witnessmenow/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?
