Description



Human-Machine Interface. An intelligent LCD that provides a lot of built-in graphics elements. Serial interface.

Available from: CircuitGizmos

Nextion is a seamless Human Machine Interface (HMI) solution that provides a control and visualization interface between a human and a process, machine, application or appliance. Nextion is mainly designed for Internet of things (IoT) devices or consumer electronics. It is the best solution to replace the traditional LCD or LED display.

Nextion includes a hardware part and a software part (the Nextion editor). The Nextion TFT board uses one TTL-level serial port to communicate. It lets users avoid the hassle of wiring. The Nextion programming editor includes commonly used components such as buttons, text boxes, progress bars, sliders, instrument panels, etc. to enrich the interface design. Drag-and-drop programming ensures that users spend less time in programming. With the help of this WYSIWYG editor, designing a GUI is a piece of cake!

It's easy to adapt Nextion family HMI to existing projects. Users just need to provide +5V and a TTL-level UART.

NX2432T024 is a powerful 2.4'' HMI, which is member of Nextion family. Features include: a 2.4" TFT 320 x 240 resistive touch screen display, 4M Flash, 2K Byte RAM, 65k colors.
