Overview
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 IoT or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tube. With the Nextion Editor software (Official Download), users are able to create and design their own interfaces for Nextion display.
The Nextion Enhanced series are more powerful compared to the Nextion Basic series. In addition to a faster MCU clock, the Enhanced series support: built-in RTC, 1K EEPROM for user data, 8 digital GPIO, larger Flash capacity, and more RAM (for models 3.5″ and higher).
Note: the small power supply test board and connecting wire inside the package allow you to test if the electrical supply is enough or not. See the image below on how to use it.

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 windows
Text-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.
