Recommendation for LCD TFT screen

Well-known member
Can anyone recommend a teensy 4.1 compatible 4inch x 4inch TFT LCD touch screen?

I'm wanting to add one to my new project.

Thanks
 
4" x 4" could be hard to find. As long as it is an Arduino compatible driver chip like ILI9341 or ST7789 then you should be fine
 
The 4x4" LCD I've used has a ST7701S 18bit RGB interface which the Teensy can not drive.

For use with the Teensy then you really need to choose between 3.5" or 4.3" in a rectangular format.

If you really must use 4x4" then the ESP32S3 is an alternative.

buydisplay.com has a large range of LCDs with documentations.
 
With a T4.1 and FlexIO3 there just might be enough pins to emulate an RGB interface for 16 bit color depth

Thank you for your answers. Pretty much the only one I have found is the adafruit https://www.adafruit.com/product/5794 display. I guess i will have to use the ESP32 as a man in the middle, seems there is no other options.

No you dont

This is exactly what you want, along with the Adafruit_GFX.h library

For ST77xx displays, they are basically the same but have different definitions for screen size in pixels. You can basically set any screen size you need
