4.0 Inches 480x320 TFT Touch Screen LCD Display Module SPI ST7796S Driver for Arduino R3/Mega2560

Very satisfied with the quality and durability of the screen. Works well for what I needed it for and hopefully other projects in the future.

The instructions and code are all on the website. However, I decided to use it with the adafruit library and it worked perfectly fine! Pretty good build quality and would buy again for the price.

It works. No dead pixels. It came well packaged. Brightness is decent. Viewing angle is limited but expected at this price. Using it with and ESP8266 NodeMCU microcontroller. No issues finding software libraries to drive it. I would buy it again if I need another one.

This smaller 320x240 display has a nicer dot pitch than the larger versions. This is my first try with a TFT and it's been an easy experience. No bad surprises and it had been easy to program.

These can work with 5V Arduinos, but require 3.3V signals. I've had other 3.3V stuff work with 5V Arduinos, so I initially tried the 2.4 inch version with NO voltage conversion. This did NOT work. I then tried using resistors to form a voltage divider to get approximately 3.3V and this did not work either. Not sure if due to an error on my part or not. Having all those resistors on a breadboard is asking for a short so there may have been one.I ended up getting the 3.5 inch version and used the level shifters listed below. This worked well. I was not sure if the 2.4 inch screen was OK or if I fried it with 5V. I tried it by swapping it directly out with the (working) 3.5 inch setup and it worked as well. It seems that while it will not work with 5V, it is not guaranteed to kill it either.I have NOT tested the SD or Touch interfaces yet.Level shifters:https://www.amazon.com/dp/B07F7W91LC?psc=1&ref=ppx_yo2ov_dt_b_product_details

The LCD works great comes with a stylus which makes it easier to select items on the screen. I used it with an ESP32-S3 and a GPS module for ESP marauder. The only downside is that it has a full size SD slot so the memory sticks a bit far off of the display.

I used this screen in a project and upon completion everything but the screen worked. I did my troubleshooting and verified it is the screen that is bad. Contacted customer servce and have been ignored. Save yourself some time and money and do not buy fom these people. .

Ok, this is great little screen and it pares up really nicely to an ESP32. Google 320x240 SPI Serial ILI9341 with ESP32. It does take a little tweaking in the Arduino IDE. There are 9 wires that go to 12 (I think) pins on the screen. There are several examples that are included with the Arduino library that will help show off the features and give code examples. I have not tried the SD card, so I cannot speak to that but a lot of other people commented on how well it works. There is an included stylus, but I really only used that during the initial setup. It is a resistive touch display, so no multi touch. The nice thing with resistive touch is that it works with gloves on.
