Add some jazz & pizazz to your project with a colour touchscreen LCD. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen! Interface this LCD to just about any microcontroller with 12 I/O available.


Additional Information [Hide]

This display has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control, this has way more resolution than a black and white 128x64 display. You'll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). 4 pins are required for the touch screen (2 digital, 2 analog) but because of the way resistive touch screens work, we can share pins with the LCD so the entire setup can be run by 12 pins (10 digital, 2 analog).

 Specifications:

  • 2.8" diagonal LCD TFT display
  • 240x320 resolution, 18-bit (262,000) color
  • ILI9325 (datasheet) or ILI9328 (datasheet) controller with built in video RAM buffer
  • 8 bit digital interface, plus 4 or 5 control lines
  • 5V compatible! Use with 3.3V or 5V logic such as an Arduino
  • Onboard 3.3V @ 150mA LDO regulator
  • 4 white LED backlight, transistor connected so you can PWM dim the backlight
  • 1x20 header for easy breadboarding, or 2x10 header for cable connection
  • 4 x 0.125"/3mm mounting holes with tabs
  • 4-wire resistive touchscreen

Dimensions:

  • Display itself is 70mm x 50mm x 4mm (2.72" x 1.97"x 0.15")
  • PCB with tabs is 82mm x 64mm (2.5" x 3.2") 
  • 4 mounting holes are 3.2mm diameter (0.13") on a 2.25" x 2.95" grid (57.5mm x 75mm)

Library:
Full open source graphics library
that can draw pixels, lines, rectangles, circles, text and full color bitmaps from an SD card . We also havea touch screen library that detects x, y and z (pressure) and example code to demonstrate all of it.

Tutorial:
A detailed tutorial
on how to use the LCD, example Arduino library and example code. The library and example code is written for Arduino but can be easily ported to your favorite microcontroller!
