Adafruit 2.8″ TFT LCD with Touchscreen Breakout Board w/MicroSD Socket – ILI9341

The 2.8″ TFT LCD with Touchscreen Breakout Board with a MicroSD Socket and an ILI9341 controller display can be used to add a graphical user interface (GUI) to a project. The TFT (thin-film transistor) LCD (liquid crystal display) has a resolution of 240×320 pixels, which allows it to display detailed images and text. The touchscreen feature allows users to interact with the display by touching the screen. The MicroSD socket can be used to store and access data from a MicroSD card. The ILI9341 controller is responsible for driving the display and handling touch input. This breakout board can be used with a microcontroller to create a GUI for a project or application.

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)

Features

• 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
• 1×20 headers for easy breadboarding
• 4-wire resistive touchscreen
• Thickness: 7.9mm / 0.3″
• Weight: 40
