The Arduino 2.8 TFT Touch shield uses the ILI9325DS controller , it support 8bit data interface. The touch IC is TSC2046.
Operation voltage level setting switch
When using the Arduino 2.8 TFT Touch shield with 5V operation level development board – like the Arduino UNO, Arduino MEGA and so on, set the operation voltage level switch to 5V side.
When using the Arduino 2.8 TFT Touch shield with 3.3V operation level development board – like the Iteaduino BT, leaf maple, chipKit UNO and so on, set the operation voltage level switch to 3.3V side.
