3.5 Inches TFT LCD Touch Screen Shield Display Module 480x320 SPI Serial ILI9488 with Touch Pen Compatible with Arduino R3/Mega2560 Development Board

If you wire it up correctly, this thing flies. It handled my specific need with ease. The touch functions work well. Fair notice, you need an Arduino Due in order to get enough speed from your micro controller to drive this high color unit. I like the fact that we can wire directly to the pins and we don’t have to use a shield. That makes it perfect for my application.

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

Beat my head against this for a month or more, every graphics library I could find, both in the Arduino IDE and in ESP-IDF (5.2.1). Finally settled on TFT_eSPI, and could get the display function working OK.In all fairness, you can brand me a Bone Head (wouldn't be the first time, and I'm sure it won't be the last . . .). The key to getting the touch function to work is by connecting the display MOSI (pin 6) to the touch T_DIN (pin 12) and the display MISO (pin 9) to the touch T_DO (pin 13). Then things came together nicely (using TFT_eSPI library in the Arduino IDE). Haven't tried the ESP-IDF version yet, that's next, but I expect it will be OK.Much happier with the display now.However, the example sketches from the product website (LCDWIKI libraries) I couldn't get to compile. I could probably spend a lot more time and maybe fix them, but I've spent enough time on this already, so I still dock it a star.

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.

This screen has been really fun to play with on my ESP32 project. Picked up 3, plan on buying more..

Product came looking like someone had several of them in a bag and shook em up.As far as the actual functionality is concerned, mine came bricked; reset function didn't work whatsoever. Returning it sadly. I should have trusted the reviews lol
