Overview
Nextion is a Seamless Human Machine Interface (HMI) solution that provides a control and visualisation 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 software - Nextion Editor , users are able to create and design their own interfaces for Nextion display.
Package include: a Nextion NX3224T024 2.4" display, a wire, a power supply test board
Note: there's a small power supply test board and a wire inside the package for you to test if the electricity supply is enough or not. Please see below image on how to use it.
