The Nextion Enhanced NX3224K024 2.4” HMI Touch Display is powerful than the standard ones. Compare to the basic Nextion displays, the enhanced ones have added some new functions, such as: supporting built-in RTC, supporting save data to Flash, supporting GPIO, larger flash capacity, and larger CPU clock. The enhanced Nextion series has 7 size covers from generic 2.4” to 7.0”.

Nextion Enhanced NX3224K024 is a powerful 2.4” HMI TFT display, with 16MB Flash data storage space, 1024 bytes EEPROM and larger RAM of 3584 bytes. With GPIO supported, now customers can use Nextion to control external devices.

Nextion Enhanced NX3224K024 – Generic 2.4” HMI Touch Display 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 the consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tubes.

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 on 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. And the drag-and-drop function ensures that users spend less time in programming, which will reduce 99% of your 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.

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