Nextion Color Touch Panel Information

The Nextion display is offered in two different product families, Basic and Enhanced. Display sizes for both families ranges from 2.4-inches (6cm) to 7.0-inches (18cm). The Enhanced version has all the capabilities of the basic model, but has more memory and includes I/O capabilities. Please note that the examples shown in this wiki have been tested on the basic version.

Here's a short YouTube video that shows examples of what you can do with a Nextion display: https://www.youtube.com/watch?time_continue=6&v=FMWQ1dXZr2I

Important Information

In addition to the two product families, there are also region specific models. More specifically, there's the Chinese market TJC series (supported by tjc1688.com) and the NX model series (supported by iteadstudio.com) that's for the general global market. The TJC site is Chinese language, the ITEAD Studio site is English.

Be aware that some sellers do not specifically mention the exact model number so avoid disappointment by choosing a different supplier. To be blunt, unless you have a project that specifically requires the Chinese market TJC display, our recommendation is to use the global market NX series.
