Nextion 2.8″ HMI Display Enhanced Series NX3224K028 Resistive LCD-TFT Touch Screen 320 * 240, with RTC Function and 8 Digital GPIOs, Suitable for IoT Smart Device, 3D Printer, etc.

These are not the easiest to use, and they are slow to program, but they are good displays for interfacing with microprocessors, and the Nextion software is pretty versatile. The only complaint I have is that there's no real manual for the software. There is an instruction set. That's about it. The screens all come with a sample program loaded. It would be very valuable if you could download that program to use as a reference. As it is now, you cannot. That's the only reason I didn't give 5 stars.

I used this touchscreen on my uBitx v.6 ham radio - even though it wasn't intended to fit. (You can search online to find a video about how to *CAREFULLY* widen out the mounting holes.) Knowing full well that I could damage the screen, I carefully proceeded and was rewarded with a gorgeous display! The touch screen has so far seemed responsive, and the display colors are just beautiful. I love this thing and would easily buy more for other projects.

It shows pictures of the battery installed when looking around at the different models. Opened the box to see that the battery doesn't come with the unit. Guess features you pay for aren't always included with the RTC functionality. Needs a CR1220.Also, if you want to use the 8 Digital GPIOs, you have to buy a separate component to use them. Nextion IO Adapter or the Nextion I/O Extended Expansion Board.

Looks great and I'm sure it will work well for my application, the demo software works well. I couldn't get any of the examples to work because it's for an older version, and the latest programming interface is incompatible with the examples, I'm afraid the learning curve may be a little too steep for me.

Product is end-of-life and hard to use, requiring legacy software. Not recommended
