2.4 inch Touch TFT LCD Display Shield
Description
2.4 inch TFT Touch Screen LCD Module for Arduino has excellent vivid color contrast.
You can Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection.
This TFT display is big,bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades).
It has way more resolution than a black and white 128A—64 display.
As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
It uses digital pins 5-13 and analog 0-3.
That means you can use digital pins 2, 3 and analog 4 and 5.
Features
2.4″ diagonal Touch LCD TFT display
240×320 resolution, 18-bit (262,000) color
8 bit digital interface, plus 4 control lines
Driver chip: HX83475G
Uses digital pins 5-13 and analog 0-3. That means you can use digital pins 2, 3 and analog 4 and 5. Pin 12 is available if not using the microSD
Works with any Arduino uno and mega compatible boards
5V compatible! Use with 3.3V or 5V logic
Onboard 3.3V 300mA LDO regulator
Working temperature: -30°C ~ 70°C
4 white LED backlight. On by default but you can connect the transistor to a digital pin for backlight control
Applications
Digital photo frame, touch handwriting board, e-book, MP3 player, handheld instrument, etc.

How does the 2.4″ TFT Color Touch Screen work?
The LCD is controlled by 8 data pins (2-9) and 5 control pins (A0-A4), the touch screen shares the data bus to send the position 100% compatible with all Arduino formats (UNO, Mega , DUE, Leonardo, etc).
A TFT needs a controller that translates the received information into the low-level signals necessary to control the panel’s electronics.
This controller will determine the connection scheme and the code that we must use.
Use with sockets without wiring, clear screen, support for touch function, Support 16-bit RGB 65K color screen, display rich colors, 8-bit parallel bus, faster than serial SPI update, built-in switching IC 5V/3.3V level, compatible with 5V/3.3V operating voltage easy to expand experiment with SD card slot, Provides Arduino library with rich sample program.
