The NX3224T028 is a display of the NEXTION family which differs from the traditional display due to the presence of a microcontroller, a flash memory, a slot for inserting an SD card containing the firmware of your project, a 4-pin TTL serial interface and a free software (Nextion Editor) specifically designed to draw the graphic part (buttons, progress bars, images, text, etc.). It has a 4 MB flash memory, a 2.8 "resistive touch screen, a resolution of 320x240 pixels and 65,536 colors.

Ideal for creating process monitoring and control applications, for displaying data, photos and videos, it can be used with Arduino, Raspberry Pi and other microcontrollers.

The package includes the touch screen display module, the 4-wire cable with connector and the adapter for micro USB power supply.

The Nextion display

Nextion is a Human Machine Interface （HMI） solution combining an onboard processor and memory touch display with Nextion Editor software for HMI GUI project development.
Using the NEXTION Editor software, you can quickly develop the HMI GUI by drag-and-drop components (graphics, text, button, slider etc.) and ASCII text based instructions for coding how components interact at display side. Nextion HMI display connects to peripheral MCU via TTL Serial (5V, TX, RX ,GND) to provide event notifications that peripheral MCU can act on, the peripheral MCU can easily update progress and status back to Nextion display utilizing simple ASCII text based instructions.

NEXTION offers a convenient Human Machine Interface solution
