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.
Software
This shield is compatible with UTFT library for Arduino, chipKit and their compatible boards. You can down load the library here: http://henningkarlsen.com/electronics/library.php?id=52
Note
Note: This shiled is 100% compatible with ITeaduino, Simplecortex. But not 100% compatible with Arduino UNO because of its big USB connecter socket.
