This 2.4 inch LCD module has 240 x 320 resolution and 65K color. It can handle most of the displaying tasks, many contents, graphs, sensor datas, user manual etc.. Also don’t worry about how to drive the display. The Adafruit’s ILI9341 Library works with this display perfectly. And don’t forget to install Adafruit GFX Library.

Note: The Display operating voltage is 3.3V, so you can connect the display pins to 3.3V MCU directly, if you need to make it work on 5V MCU, make sure to use a logic level translator.

ILI9341 is a 262144-color single-chip SOC driver for a TFT liquid crystal display with resolution of 240x320 dots (RGB), comprising a 720-channel source driver, a 320-channel gate driver, 172800 bytes GRAM for graphic display data of 240x320 dots (RGB), and power supply circuit.

ILI9341 supports parallel 8-/9-/16-/18-bit data bus MCU interface, 6-/16-/18-bit data bus RGB interface and 3-/4-line serial peripheral interface (SPI).

ILI9341 can operate with 1.65V ~ 3.3V I/O interface voltage and an incorporated voltage follower circuit to generate voltage levels for driving an LCD.

ILI9341 supports full color, 8-color display mode and sleep mode for precise power control by software and these features make the ILI9341 an ideal LCD driver for medium or small size portable products such as digital cellular phones, smart phone, MP3 and PMP where long battery life is a major concern.

This 3.2″ TFT LCD is a full color display with a resolution of 240 x 320 pixels or 320 x 240 pixels depending on how it is oriented.  It uses the ILI9341 controller with SPI interface.  It also includes a resistive touchscreen with built-in XPT2046 controller.

These full color displays are large enough for many applications even when using touch.  The supplied stylus is helpful when using smaller touch targets.

Internally the display operates at 3.3V, so if using with a 5V microcontroller, be sure to include        logic level shifters on the data lines to prevent possible damage.

The module power comes in on the Vcc pin.  The module includes an on-board 3.3V regulator, so the module should normally be operated off of 3.6 to 5.5V power on this pin to feed the regulator.  Current is typically 55-60mA

If you would prefer to operate the module directly from a 3.3V power source, there are two solder pads labeled J1.  By solder shorting these two pads together, the regulator is bypassed and the module can be powered directly from 3.3V.

In general, it is best to operate the display off of 5V to ensure enough power is available.  Be careful of trying to operate the display from the built-in 3.3V available on Arduino and similar microcontrollers since these power sources often have limited current capability and may overheat.

These are interesting modules to work with since they have full color and graphical capability with good library support and the touch capability adds a new dimension of usefulness.

These modules are breadboard friendly with a 14-pin header on the back that can be inserted into a solderless breadboard or a 14-pin female connector can be used to connect to it if the display is to be mounted.  The display is mounted on a stiff PCB that provides good support, but be sure to press on the header pins or PCB when applying pressure to insert them into a breadboard and not press on the glass to avoid possible damage.

Though these displays can seem to be a bit intimidating to use at first, just follow these steps to get up and running fairly easily.  The pin labeling is on the back only, so we have pictures with the pins labeled on both the front and back to make life a little easier.

I’m also using the Teensy 4.1 because it is currently the fastest Arduino compatible board (600MHz 32-bit vs Uno 16MHz 16-bit) and this example application of calculating Mandelbrot fractals and updating the LCD can take a long time on an Uno (77-105 seconds) and only takes about 1.25 seconds on the Teensy 4.1.  If using a 3.3V Arduino like a Due, hookup will basically be the same.

Connect the SPI and control lines for the display.  In our example we are using hardware SPI as it gives the best performance.   The SPI pin location will depend on the MCU you are using.

If you just want to check the display functionality and speed, the ‘graphicstest’ example program installed as part of the Adafruit_ILI9341 library is a good one to run.

The program below is a modified version of the Mandelbrot example program that gets installed with the Adafruit_ILI9341 library.  It was pruned down in size and basic touch added.  The program just calculates the Mandelbrot set and draws it to the screen pixel-by-pixel as it is calculated.  The math is fairly intense for each pixel, so it is a good judge of the power of the MCU.  The display update speed is thus limited by the MCU that is doing the calculations and is not limited by the display itself.

TFT LCD module has always been one of the hot products in DIY industry and LCD is basically the necessary products during all projects, at the same time, serial port modules are also the popular ones, because it takes few IO and the usage is simple. This section of the 2.4S-inch TFT LCD serial SPI integrated features of compact, SPI interface.

The LCD drive ic is ILI9341. It"s a 240 * 320 (resolution), 2.4 inch TFT LCD screen.The LCD has a wide viewing angle, the contrast is also very suitable.

This 2.8 Inch SPI TFT LCD ILI9341 5V 240X320 Module is a full color display with a resolution of 240 x 320 pixels. It uses the ILI9341 controller with SPI interface. It also includes a resistive touchscreen with built-in XPT2046 controller.

As a bonus, this 2.8 Inch SPI TFT LCD ILI9341 5V 240X320 Module 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 the 8-bit mode. In addition, 4 pins are required for the touchscreen (2 digital, 2 analogs).

This 2.8 Inch SPI TFT LCD ILI9341 5V 240X320 Module is wrapped up 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 Micro SD card socket to display images.

Internally the display operates at 3.3V, so if using with a 5V microcontroller, be sure to include logic level shifters on the data lines to prevent possible damage.
