Nextion is a Human Machine Interface (HMI) solution. Nextion is a resistive touchscreen display that makes it easy to build a Graphical User Interface (GUI). It is a great solution to monitor and control processes, being mainly applied to IoT applications.
About Nextion Display
The Nextion has a built-in ARM microcontroller that controls the display, for example it takes care of generating the buttons, creating text, store images or change the background. The Nextion communicates with any microcontroller using serial communication at a 9600 baud rate.
So, it works with any board that has serial capabilities like Arduino, Raspberry Pi, ESP8266, ESP32, and so on. Learn how to use the Nextion display with the Arduino.
The Nextion display comes with different screen sizes and resolutions:
- 2.4″ – 320*240
- 2.8″ – 320*240
- 3.2″ – 400*240
- 3.5″ – 480*320
- 4.3″ – 480*272
- 5.0″ – 800*480
- 7.0″ – 800*480
The best model for you depends on your needs. If you’re just getting started with Nextion, we recommend getting the 3.2″ size which is the one used with the official Nextion Arduino library examples (the examples also work with other sizes, but you need to make some changes).
