There is an ESP32 with a built in 320 x 240 LCD display with a touch screen called the "ESP32-2432S028R", since this doesn't roll of the tounge, I propose it should be renamed the "Cheap Yellow Display" or CYD for short. This display is only about $15 delievered so I think it's really good value.
The CYD has the following features:
- ESP32 (With Wifi and Bluetooth)
- 320 x 240 LCD Display
- Touch Screen (Resistive)
- USB for powering and programming
- SD Card Slot, LED and some addtional pins broken out
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 familar 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.
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 benifit 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.
Buy from wherever works out cheapest for you:
- Aliexpress*
- Aliexpress*
- Aliexpress
- Makerfabs - Seems to come with a 16GB SD card. Makerfabs also stock my ESP32 Trinity
* = Affilate Link
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. Check them out here.
