Nextion is a Human Machine Interface (HMI) solution combining an onboard processor and memory touch display with Nextion Editor software for HMI GUI project development. Using the NEXTION Editor software, you can quickly develop the HMI GUI by drag-and-drop components (graphics, text, button, slider etc.) and ASCII text-based instructions for coding how components interact at the display side. Nextion HMI display connects to peripheral MCU via TTL Serial (5V, TX, RX ,GND) to provide event notifications that peripheral MCU can act on, the peripheral MCU can easily update progress and status back to Nextion display utilizing simple ASCII text-based instructions.

The Intelligent Series products have more powerful hardware in terms of MCU, Flash storage and SRAM compared with Basic Series and Enhanced Series. What’s more and new? The audio, video and animation play functions enrich user’s project HMI interaction. The Intelligent Series supports advanced software features and functions such as transparent components, page loading effect, component Move and Drag .etc.

Package include: Nextion NX4827P043-011R HMI Display*1, XH2.54 4P wire*1, power supply test board*1.
Note: the small power supply test board and connecting wire inside the package allow you to test if the electrical supply is enough or not. See the image below on how to use it.
