Now available as a shield for Arduino UNO, this 2.4-inch TFT touch screen module comes with a micro SD card slot. It features a four-wire resistive touch screen, a micro SD card socket, a reset switch, and a convenient Arduino Uno shield footprint. The screen offers 18-bit color with 262,000 different shades and is brightly lit by 4 white LED backlights, which can be controlled via a digital pin. It works with any Arduino 328 or Mega (Leonardo not supported yet). The specifications include a 2.4-inch diagonal LCD TFT display with 240×320 resolution, 5V compatibility, an onboard 3.3V 300mA LDO regulator, an 8-bit digital interface plus 4 control lines, and a 4-wire resistive touchscreen. It uses digital pins 5 - 13 and analog 0 - 3, leaving digital pins 2, 3 and analog 4, 5 available. Pin 12 is free if you don't use the microSD. The package includes one 2.4-inch TFT Touch Shield for Arduino. Also, you can find the ILI9341 Datasheet, Schematic, and Arduino Demo code.

Using this 2.4-inch TFT touch shield for your Arduino is easy. First, make sure your Arduino is an Arduino 328 or Mega (it won't work with Leonardo for now). Connect the shield to your Arduino following the pin usage details provided. You can use it with either 3.3V or 5V logic. The backlight is on by default, but if you want to control it, connect the transistor to a digital pin. When using the micro SD card slot, insert your card carefully. If you're not using the microSD, you'll have pin 12 available for other uses. As for maintenance, keep the shield in a clean and dry place. Avoid exposing it to extreme temperatures or physical shocks. And always double - check your connections before powering on your Arduino to prevent any damage.
