Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful! 240x320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128x64 display.


Additional Information [Hide]

As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

This display has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. The display can be used in two modes: 8-bit and SPI. For 8-bit mode, you'll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). SPI mode requires only 5 pins total (SPI data in, data out, clock, select, and d/c) but is slower than 8-bit mode. In addition, 4 pins are required for the touch screen (2 digital, 2 analog).

We wrapped up this display into an easy-to-use breakout board, with SPI connections on one end and 8-bit on the other. Both are 3-5V compliant with high-speed level shifters so you can use with any microcontroller. If you're going with SPI mode, you can also take advantage of the onboard MicroSD card socket to display images. (microSD card not included, but any will work)

 Specifications:

  • 2.8" diagonal LCD TFT display
  • 240x320 resolution, 18-bit (262,000) color
  • ILI9341 (datasheet) controller with built in video RAM buffer
  • 8 bit digital interface, plus 4 or 5 control lines (12 pins minimum) or SPI mode with 4 or 5 SPI data/control lines (4 pins minimum) - not including the touch screen.
  • 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 headers for easy breadboarding
  • 4-wire resistive touchscreen
  • 40g

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!
