base on Building a community around a cheap ESP32 Display with a touch screen # 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?  ## Where to buy? Buy from wherever works out cheapest for you: - [Aliexpress\*](https://s.click.aliexpress.com/e/_DkSpIjB) - [Aliexpress\*](https://s.click.aliexpress.com/e/_DkcmuCh) - [Aliexpress](https://www.aliexpress.com/item/1005004502250619.html) - [Makerfabs](https://www.makerfabs.com/sunton-esp32-2-8-inch-tft-with-touch.html) - Seems to come with a 16GB SD card. Makerfabs also stock my [ESP32 Trinity](https://github.com/witnessmenow/ESP32-Trinity) (NOTE there will be import due in the EU from makerfabs) \* = Affiliate Link ## Getting Started With Your CYD For details on how to get started with your CYD, please check out the [Setup and Configuration](/SETUP.md) page ## Code Examples ### 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.](/Examples/Basics) ### 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.](/Examples/AlternativeLibraries) ### ESPHome Some examples for using the CYD in ESPHome. [Check them out here.](/Examples/ESPHome) ## Additional Info and Links ### Discord Join the CYD discussion on [my Discord channel](https://discord.gg/nnezpvq) ### 3DPrinting Some examples of 3D printed stands and cases. [Check them out here.](/3dModels) ### Pin Information [This page](/PINS.md) contains information about what pins are used where, and what ones are free to use. ### Add-ons [This page](/ADDONS.md) contains information about additional hardware add-ons that can add functionality to your CYD ### Troubleshooting [This page](/TROUBLESHOOTING.md) contains information about how to troubleshoot your CYD device ### Hardware Mods [This page](/Mods/README.md) contains information about some hardware mods that can be performed on the CYD to improve or change some of its functionality ### Media and Video Mentions [This page](/MEDIA.md) lists any times the CYD project was mentioned somewhere! ## License Info This project is licensed as MIT as per the [license file](/LICENSE) The one exception to this is the [OriginalDocumentation](/OriginalDocumentation/) folder, that I do not have the right to license ## Other Languages Some members of the community have ported some of this information to other languages!
