Nextion Discovery 2.4" HMI Touch Display

Nextion Discovery NX3224F024 is a powerful 2.4'' HMI TFT display with 4MB Flash data storage space and RAM of 3584 bytes. Nextion is a Seamless Human Machine Interface (HMI) solution that provides a control and visualisation interface between a human and a process, machine, application or appliance.

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. 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. With the help of this WYSIWYG editor, designing a GUI is a piece of cake.

It is easy to control the display with these libraries for Arduino and Raspberry. This display can also operate stand-alone, as can be seen in this example.
