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 Nextion Editor software (Official Download), users are able to create and design their own interfaces for Nextion display.

The Nextion Enhanced series are more powerful compared to the Nextion Basic series. In addition to a faster MCU clock, the Enhanced series support: built-in RTC, 1K EEPROM for user data, 8 digital GPIO, larger Flash capacity, and more RAM (for models 3.5″ and higher).
