The enhanced Nextion versions are more powerful. Compared to the basic Nextion displays, the new ones have added some new functions: support for built-in , support for saving data to Flash, support for GPIO, larger flash capacity and faster CPU. The Nextion Enhanced NX3224K024 is a powerful 2.4-inch HMI TFT display, with 16 MB Flash data storage space, 1024 bytes EEPROM, 3584 bytes RAM. With GPIO support, you can now use Nextion to control external devices. Nextion is a seamless Human Machine Interface (HMI) solution that provides a control and visualization interface between a human and a process, machine, application or appliance. It is the best solution to replace the traditional LCD and LED Nixie tube. Nextion includes hardware part (a series of TFT boards) and software part (Nextion editor). The Nextion TFT board uses only one serial port to communicate. It lets you avoid the hassle of wiring. We notice that most engineers spend a lot of time on application development but get unsatisfactory results. In this situation, the Nextion editor has mass components such as button, text, progress bar, slider, dashboard etc. to enrich your interface design. And the drag-and-drop function ensures that you spend less time on programming, reducing 99% of your development workloads. With the help of this WYSIWYG editor, it is easy to design a GUI. It is easy to adapt the Nextion family HMI to existing projects, you only need to provide a UART. Note: there is a small test board for power supply and a wire for you to test whether the power supply is sufficient or not.
