Greeatings .
I need some help with pcb design for this mcu.
Are ILI 9431 and ILI 9488 same.
Have someone pcb design for that mcu with atmega ???
I have never heard of an ILI9431.
ILI9488 is a 320x480 TFT controller.
These TFT controllers are generally surface mounted on the TFT panel. You can't even see them.
They generally run at 2.8V or 3.3V. You need level-shifters to connect with a 5V Arduino.
Life is simpler with a 3.3V Due or Zero.
Someone with a similar "unusual" name has asked several questions on TFT subjects. If you are the same person, you have already had many replies.
