This TFT screen is really big (3.2" diagonal), bright (6 white LEDs) and colorful! 240x320 pixels with individual RGB pixel control, which offers a much higher resolution than a 128x64 black and white display. As an added bonus, this screen is already equipped with a resistive touch screen, so you can detect finger pressure anywhere on the screen.

This display has an integrated controller with RAM buffer, so the microcontroller does virtually no work. The display can be used in two modes: 8 bit and SPI. For 8-bit mode, you will need 8 lines of digital data and 4 or 5 lines of digital control to read and write on the screen (12 lines in total). SPI mode requires only 5 pins in total (SPI input data, output data, clock, selection and d/c) but is slower than 8-bit mode. In addition, 4 pins are required for the touch screen (2 digital, 2 analog) or you can purchase and use our resistive touch screen controller (not included) to use I2C or SPI.

We have integrated this screen on an easy to use card, with SPI connections on one side and 8 bits on the other. Both are 3-5V compatible with high-speed level switches, so you can use them with any microcontroller. If you choose SPI mode, you can also use the built-in MicroSD card to display images. (microSD card not included, but any will work)

Of course, we won't leave you only a technical sheet and a "good luck". For 8-bit interface fans, we have written a complete open source graphics library that can draw pixels, lines, rectangles, circles, text and more. For SPI users, we also have a library, separate from the 8-bit library since both versions are highly optimized. We also have a library for touch screens that detects x, y and z (pressure) and example code to demonstrate all this.
