2.8 inch Nextion TFT HMI LCD Touchscreen NX3224T028 is a Seamless Human Machine Interface (HMI) solution. 2.8 inch Nextion TFT HMI LCD Touchscreen NX3224T028 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 thing (IoT) or the 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 with a UART.

We are also selling Nextion touchscreen in different sizes like 2.4″, 3.2″3.5″4.3″7″ etc.
