good Morning,
I have a display 2.8 '' TFT 320x240 u / touch screen for Raspberry.
I can connect it to an Arduino board? I have to replace the shield? With what?
Thank you so much for the information

Re: Adafruit 2,8'' Display and Arduino
The Raspberry Pi version does not have any level shifting for the 5V Arduino logic signals. If you connect it directly to a 5V Arduino you will damage the display (you could connect it directly to an Arduino Due, which uses 3.3V logic).
There is a schematic on the Downloads Page of tutorial. The GPIO pinout is in the upper left. You would have to connect the MOSI, MISO, and SCLK lines to the SPI pins on your Arduino. If you then connect TFT_CS to Arduino pin 10, TFT_DC to pin 9, and RT_CS to pin 8, the Adafruit_ILI9341 library ought to work.
Remember to connect MOSI, SCLK, TFT_CS, TFT_DC, and RT_CS through a level shifter to bring those signals down to 3.3V.
