This colour 2.8” TFT display has 4 bright white LED backlight and 240 x 320 pixels with individual RGB pixel control. It has a resistive touchscreen to detect finger presses anywhere on the screen. The built-in controller has RAM buffering to take the workload away from the microcontroller. This display board has two modes: 8-bit and SPI.

When using 8-bit mode, you need 8 digital data lines and 4 or 5 digital control lines to read and write to the display.

SPI mode requires only 5 pins total (SPI data in, data out, clock, select, and dc) but is slower than 8-bit mode.

In addition, 4 pins are required for the touch screen (2 digital, 2 analogue).

It is 3 V to 5 V compliant with high-speed level shifters so you can use with any microcontroller. If you are using SPI mode, you can also take advantage of the on-board micro-SD card socket.
