Nextion Enhanced NX3224K024 is a powerful 2.4'' HMI (Human Machine Interface) TFT display. With 16MB Flash data storage space, 1024 bytes EEPROM, and 3584 bytes RAM, a large amount of codes and data can be processed. With GPIO supported, now customers can 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. Nextion is mainly applied to the Internet of Things (IoT) or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tube.


Nextion includes a hardware part (a series of TFT boards) and a software part (the Nextion editor). The Nextion TFT board uses only one serial port to communicate. It lets users avoid the hassle of wiring. We noticed that most engineers spend much time in application development but get unsatisfactory results. As a solution to this situation, Nextion editor has mass components such as button, text, progress bar, slider, instrument panel, etc. to enrich the interface design. Furthermore, the drag-and-drop function ensures that users spend less time in programming, which will reduce 99% of their development workloads. With the help of this WYSIWYG editor, designing a GUI is a piece of cake. It's easy to adapt Nextion family HMI to existing projects- users just need to provide it a UART. To use the software, you need to program according to the Nextion instruction set. Nextion editor guide can help you set up the Nextion editor software.



There's a small power supply test board and a wire for you to test if the electricity supply is enough or not. Please see below image on how to use it.
