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 faster CPU. The enhanced Nextion series has 7 size covers from generic 2.4'' to 7.0''.
Nextion Enhanced NX4832K035 is a powerful 3.5'' HMI TFT display, with 32MB Flash data storage space, 1024 byte EEPROM, 8192 byte RAM. With GPIO supported, now you can use Nextion to control external devices.
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. It is the best solution to replace the traditional LCD and LED Nixie tube.
Note : there's a small power supply test board and a wire for you to test if the electricity supply is enough or not. Please see below image how to use it.
