Nextion Discovery NX3224F028 HMI Display 2.8 Inch 320x240 with Touchscreen

Complete HMI display with touchscreen. This display can be controlled serially via a UART port. The graphical interface of this module can be programmed via an SD card or via the UART connection.
Decide for yourself what the screen looks like and program the interface with the touchscreen yourself. See the following page for examples and libraries for the Arduino IDE: GitHub
