NX3224K028 Nextion 2.8 inch Enhanced Display 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 the 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 versions are more powerful than the standard ones. Compared to the basic Nextion displays, the enhanced ones have added some new functions, such as: supporting built-in RTC, saving data to Flash, supporting GPIO, larger flash capacity and larger CPU clock.
