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 (Official Download), users are able to create and design their own interfaces for Nextion display.
The Nextion Enhanced versions are more powerful. Compare to the basic Nextion displays, the new ones have added some new functions: support built-in RTC, support save data to Flash, support GPIO, larger flash capacity and larger CPU clock. The enhanced Nextion series has 7 size covers from generic 2.4 to 7.0.
Nextion Enhanced NX3224K028 is a powerful 2.8" HMI TFT Touch Display, with 16MB Flash data storage space, 1024 byte EEPROM, 3584 byte RAM, and GPIO supported.
