Nextion NX4024T032 3.2-inch HMI Touch Display – Basic Series TFT LCD Panel, 320x240 Resolution, UART Serial Communication, for Arduino/Raspberry Pi/ESP32, DIY Smart Home & Industrial Control

Added "HMI" Context – Explicitly includes "Human Machine Interface" in parentheses (matches technical searches).

Highlighted IoT & Electronics – Added "for IoT & Electronics" (aligns with Nextion’s primary applications).

Simplified Technical Terms – Kept "UART Serial Interface" (clearer than "Communication").

Retained High-Traffic Keywords – Still includes Arduino/Raspberry Pi/ESP32 (critical for DIY audience).

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 Internet of thing (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. NX4024T032 is a powerful 3.2” HMI, which is member of Nextion family. Features include: a 3.2″ TFT 400×240 resistive touch screen display, 4M Flash, 2KByte RAM, 65k colors.

3.2″ Nextion NX4024T032 HMI TFT Intelligent Display Module Package include: a Nextion 3.2” display, a wire, a power supply test board Note: 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 how to use it.Check out the amazing features of this product below.

Nextion Editor Overview Nextion Editor is a free human-machine interface (HMI) GUI development software for Nextion Basic Series, Discovery Series, Enhanced Series, and Intelligent Series. The software offers an easy way to create an intuitive and superb touch user interface even for beginners. Add a static picture as a background, define functions by components, you can make a simple GUI in minutes. The easy Drag-and-Drop components and simple ASCll text-based instructions will dramatically reduce your HMI project development workloads and develop projects rapidly in a cost-effective way. The Nextion product is the best balance HMI solution between cost and benefit with a low and decreased learning curve.Nextion Editor Features Versatile Character Encoding With several character encoding, you are able to create the HMI project in your language characters and strings. Fonts and Text Styling The font creator allows you to generate the specific fonts applied in each component value or text attribute. e.g.Generate the font of “Arial” with Height “24” and Encoding “UTF-8”25+Amazing WYSIWYG Components Easy-to-use components to customized GUI at screen side allow you to develop projects rapidly in a cost-effective way Component Attribute Setting The component attribute setting gives you the options to design all the aspects of the component that you need.Free Simulator Debug Debug the HMI project at any time even without the Nextion Display.The instruction input area allows you to send any Nextion commands to check the feedback and interactions. Nextion Operational Commands The operational commands allow users to program the HMI interactions by coding in Events windowsText-based Instruction Set Simple ASCll text based instructions will dramatically reduce your HMI project development workloads Support Simple Assignment Operators To handle the calculation and assignment for the text and Numeric data, the simple assignment operators help.
