waveshare General 2inch IPS LCD Display Module 240×320 Resolution 2.0inch Monitor Embedded Controller RGB, 262K Color Display Color LED Backlight ST7789 Driver SPI Interface

Great little screen. Works very easily on my RPi Zero 2 projects.

Works well. The driver library and demo code are good.

In the past, the main drawback of TFT technology has been the low contrast. Using In-Plane-Switching (IPS), the color is induced in the same plane as the backlight (The term would be wrong in this case, as the light plane is no longer behind the color plane), resulting in very high contrast. This display looks like an OLED display, without the drawbacks of color-fading over time, and price. Driver software is widely available - in the picture I'm using the sample from circuitpython for this chip. So far I have only driven the SPI at 24 Mhz, which the driver chip handles without hiccup. With the high contrast, this 2 inch display is as readable as bigger displays. The resolution of 240x320 gives fine detail, but obviously requires longer for screen refresh, so it's a trade off. For me, IPS displays will be the choice if available, and this display does not disappoint. The board allows for through-hole soldering of your own wires, and the supplied connector with breadboard friendly wires makes prototyping a snap, no soldering required. I will probably use this display for my final result, but will take the connector off, as it requires too much space below the display board. I tested several displays of different sizes and technologies. So far this is my favorite. What I haven't done yet is a power consumption comparison. When only few pixels are "active", OLED would usually consume less power, but I will see how it pans out.

Very good after some tinkering. I wanted to use it with Arduino to create a device for measuring how fresh the coffee pots at the office were. The provide code on the website was only for Arduino Uno. I had to tinker a bit to get it to work on Arduino Nano. I ended up removing the Chinese fonts from the drivers to save on space so it would upload successfully. The display was very slow to update though. I wanted to update specific sections of the screen, which required me to clear that section before updating the text. I ended up just writing new text with a black background to cover the old text, which worked ok. I also ended up moving to an ESP board to improve the speed a bit. The code would not compile for the ESP board. I ended up using ChatGPT to help remove the code related to the CN fonts, which is where the compile error was. I also had to explicitly set SPI.setFrequency(10000000); and change the default CS and DC pin since they seem to interfere with the ESP's bootup. Overall, it's a good value for what I paid. I was able to use it for the project that I wanted.
