NX4024K032 + Clear Case

First time user. I struggled with getting this working on my ESP32. There are several tutorials advising to do this or that, and at the same time some of the support files have already been adjusted to correct for those issues so they are outdated. I found the easiest way to get started is by watching the videos by CheapControls.com where they demonstrate how to utilize the display without the need for Nextion header files. Although they use an Arduino rather than a ESP32, there is not much difference.

For Halloween, I have designed and built several wireless LED Light Towers that displays 26 LED Lighting Effects, 23 different repeating Effects along with 3 Audio VU Effects using Arduino Nano & Uno Microprocessors. The initial control unit design required 7 pushbuttons and 2 potentiometers to access/control the various Lighting Effects. A drawback was: to access Effect #23 required scrolling through Effects 1 through 22 to get there.This Touchscreen provides immediate access to the desired LED Lighting Effect and makes the Control Box construction a breeze as well as clean and streamlined.(as opposed to drilling multiple holes and labeling for the buttons/pots and the associated wiring).There was a short learning curve for programming and setup of the Touchscreen. Interfaced with both Uno & Nano easily and reliably. Found the Nextion software easy to use once I understood the logic behind the software operation.I highly recommend the Nextion Touchscreen! For myself, this Operate Interface will be used for all future projects requiring Display and Control.

This is an excellent intelligent display. The programming tool is good but could be better and the documentation is boardering in non-existant.If you want an intelligent display that requires little programming on the target side this is good display.

The item arrived a day before scheduled delivery. Hardware all worked very well, and even the case came with extra hardware as the "carpet gods" occasionally demand sacrifice of the small screws, nuts, and spacers. What was not clear in the product listing is you need either a micro SD card or a USB to serial adapter in order to program it. I had the USB adapter already so all was OK. Unlike an Arduino, there's no USB programming port.Documentation on the Nextion site is sketchy at best for the beginner. If you're learning this device, plan on watching a lot of Youtube and digging on Google for coding ideas to get you started to develop your own application for the device. Since we're now shut in, and looking for a challenge, it's been enjoyable to be making with it, and "beating it into submission".

If I move my head 2 inches to the left, the background is silver (like it should be). If I move my head 2 inches to the right, the background is black. What have they done to produce a TFT screen with such poor parallax characteristics? The Nextion hardware and programming system is basically a good concept and does have the potential to be a first rate development system, but the parallax problem is very disappointing.If you want to do a simple (tech school level) demo project, you will find the Nextion website info adequate. But if you want to build a real-world device with a Nextion display, you'd better be willing to dig deep and get ready to invent your own wheels to make things work. And if you want to use the full potential comm speed (up to 921600 baud) - be prepared for a lot of trial and error to figure things out, because apparently Nextion keeps secrets like these to themselves.Do your self a favor - rig up a switch connecting the Nextion TFT to either your MCU or PC/USB programmer. That way you can do Uploads, run the simulator, or operate normally (MCU to TFT) merely by flipping a switch (instead of fumbling with SD cards or DuPont connectors).Like I said above - the system does have good potential, but it lacks certain professional polish that I would expect from a refined product.

This screen works well and is forgiving if you upload the wrong screen layout--just boot from a microSD card with a different layout file.

I purchased this screen to use with a ham radio jumbo spot hotspot. There is considerable information on the web on how to make this happen. The acrylic housing is very nice. This is the genuine article. You won’t be disappointed.

Very nice Nextion display works with USB power . I would recommend it I have a couple of them.

It took me some time to learn how much it was able to do, but it has more power than I expected. Works very well and is simple to interface with. I am very happy with this display. I will be buying more of these, For Sure.
