2.2 ″ 18-bit color TFT LCD display with microSD card breakout - ILI9340

Description

This lovely little display is the best way to add a small, colorful display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even with very little memory and few pins available!

The 2.2 ″ display has 320 × 240 color pixels. Unlike the low cost “Nokia 6110” and similar LCD displays, which are CSTN type and thus have poor color and slow refresh, this display is a true TFT! The TFT driver (ILI9340) can display full 18-bit color (262,144 shades!). And the LCD will always come with the same driver chip so there's no worries that your code will not work from one to the other.

The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator and a 3 / 5V level shifter so you can use it with 3.3V or 5V power and logic . We also had a little space so we placed a microSD card holder so you can easily load full color bitmaps from a FAT16 / FAT32 formatted microSD card. The microSD card is not included, but you can pick one up here.

Of course, we wouldn't just leave you with a datasheet and a "good luck!" - we've written a full open source graphics library that can draw pixels, lines, rectangles, circles, text and bitmaps as well as example code. The code is written for Arduino but can be easily ported to your favorite microcontroller! Wiring is easy, we strongly encourage using the hardware SPI pins of your Arduino as software SPI is noticeably slower when dealing with this size display. Check the example sketches for wiring help until we get a detailed wiring tutorial written!
