Nextion Enhanced 2.8 inch 320x240 TFT Touch Display

The Nextion NX3224K028 from iTead is a TFT display with 2.8 inches, 320 × 240 pixels and resistive touchscreen from the Enhanced series. The user interface is designed in the Nextion Editor on the computer and loaded onto the display; a microcontroller such as Arduino, ESP8266, ESP32 or Raspberry Pi then controls it with simple commands via the serial interface. Compared to the Basic series, the Enhanced series has more flash memory, a real-time clock (RTC), 1024 bytes of EEPROM and 8 GPIO.
