2.4 TFT LCD Touch shield

Overview

Arduino 2.4" TFT LCD Touch shield is an Arduino UNO/ Mega compatible multicolored TFT display with touch-screen and SD card socket. It is available in an Arduino shield compatible pinout for attachment. The TFT driver is based on S6D112 with 8bit data and 4bit control interface.

The Arduino 2.4" TFT LCD Touch shield can work with both 3.3V and 5V, so it can dispaly on Chipkit UNO32 and Simplecortex as well.

Features

• Compatible with 3.3/5V operation voltage level
• Compatible with UTFT library
• With SD Card Socket

The Arduino 2.4“E TFT Touch shield uses the S6D1121 controller , it support 8bit data interface. The touch IC is TSC2046.

Operation voltage level setting switch

When using the Arduino 2.4”E 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 2.4“E 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.
