In 2014, with a strong market sensitivity, Itead Studio seize the initiative to develop a new TFT display called Nextion TFT Human Machine Interface（short for Nextion below）.
What is the Nextion?
Nextion is a Seamless Human Machine Interface (HMI) solution that provides a controllable and visualized interface between a human and a process, machine, application or appliance. Nextion is mainly applied to IoT or consumer electronics field. Nextion provides a complete, high-quality display features for developing advanced graphical embedded applications in a smaller RAM, lower frequency MCU and a lower cost even. Undoubtedly, it is the best solution to replace those traditional LCD and LED Nixie tube.
Previously, engineers have only two choices for designing GUI. Some engineers choose LCD module which requires to write a mass of of source codes, which is a time-consuming and complicated job, not to mention the result may be unpleasant; While other engineers had to pay a large sum of money to buy large size expensive industrial level HMI display in the market. In most cases, a small size HMI displays means lower costs and more choices. Thanks to Itead Studio team, with their Nextion now available in the market, these problems no more exist.
Nextion Competitive Edge
Why Nextion beats other displays in the market? See below comparison table:
| Code Required | Size | Price | Function | |
|---|---|---|---|---|
| Nextion | NO | Complete | High cost-effective | High |
| Traditional LCD Modulel | YES | Small | Low | Single-function |
| Industrial HMI | NO | Large | Very High | High |
Nextion is characterized by
*Complete size displays(2.4",2.8",3.2",3.5",4.3",5.0",7.0")
*One serial port communicate with MCU *Fully functional software-a WYSIWYG editor *Character string commands, reduce debugging difficulty
*Objective-oriented controlling method, easily change component attribute properties. *Online Simulator Function
*Great compatibility-Nextion can work with all MCU boards with TX, RX serial port, such as Arduino, MCU-51, Raspberry Pi, PC, etc.
How to use Nextion?
Nextion solution includes the hardware part - a series of TFT displays and the software part - Nextion editor, where you can design your interface. After the designing in the software, you can run the interface you designed in 2 ways. 1.Upload your interface to a USB-TTL board through connecting your PC, and the TX and RX connect to Nextion TFT display. 2. Copy your tft file to a SD card, then insert it to Nextion display to download it.
Nextion TFT displays use only ONE serial port to do communicating, which helps you get rid of the wiring trouble. Nextion editor has mass components to meet your design requirements, such as button, text, progress bar, slider, timer, variable, gauge,waveform, etc. Simply drag and drop these components to the editing window to automatically compile, no need to spend much time to program for these components any more. Also, you can online simulate your interfaces in Debug window. Now you can design your interface in just 5-10 minutes, Nextion Editor reduces your 99% development workloads! With the help of this WYSIWYG editor, GUI designing is just a piece of cake.

Nextion TFT HMI display is the best choice I can find in the current market. Formerly when I was designing my own projects, I used the so-called LCD and wrote a lot of code, which really got me headache. I always wondered why there is no better choice. Now Nextion is it. You cannot miss it. Get your own brand-new Nextion now.
