2.8 Inch Nextion HMI serial Display for Arduino Raspberry Pi

DESCRIPTION

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.If the screen does not light, please check power supply voltage (5V) and polarity. If correct please ensure the correct functionality of the 3.3V regulator U1; as there is no protection circuit, this may become damaged. This can be replaced with a medium level of skill.

Nextion is the international Version, it can connect the Nextion Editor smoothly in English.If you take the TJC Version to connect Nextion Editor, it’ll show incorrect code.

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.

Nextion includes hardware part (a series of TFT boards) and software part (the Nextion editor). The Nextion TFT board uses only one serial port to communicate. It lets you avoid the hassle of wiring. We notice that most engineers spend much time in application development but get unsatisfactory results.

In this situation, Nextion editor has mass components such as button, text, progress bar, slider, instrument panel etc. to enrich your interface design. And the drag-and-drop function ensures that you spend less time in programming, which will reduce 99% of your development workloads. 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, you just need to provide it a UART.

NX3224T028 is a powerful 2.8” HMI, which is member of Nextion family. Features include: a 2.8″ TFT 320×240 resistive touch screen display, 4M Flash, 2KByte RAM, 65k colors.
