Overview

3.2 TFT LCD TOUCH SHIELD.jpg

Arduino 3.2" TFT LCD Touch shield is an Arduino Mega compatible multicolored TFT display with touch-screen and SD card socket. It is available in an Arduino MEGA shield compatible pinout for attachment. The TFT driver is based on SSD1289 with 8bit data and 4bit control interface.

The Arduino 3.2" TFT LCD Touch shield can work with both 3.3V and 5V, so it can dispaly on Chipkit MAX32 as well.

The Arduino 3.2” Touch shield uses the SSD1289 controller , it support 16bit data interface. The touch IC is XPT2046.

Operation voltage level setting switch

When using the Arduino 3.2 TFT Touch shield with 5V operation level development board – like Arduino MEGA and so on, set the operation voltage level switch to 5V side.

When using the Arduino 3.2 TFT Touch shield with 3.3V operation level development board set the operation voltage level switch to 3.3V side.

Software

This shield is compatible with UTFT library for Arduino Mega, chipKitMax32 and their compatible boards. You can down load the library here: http://henningkarlsen.com/electronics/library.php?id=52
