Nextion is a Human Machine Interface (HMI) solution that integrates a touchscreen display with an onboard processor and memory, paired with the Nextion Editor software for efficient GUI development. Using the Nextion Editor, developers can easily build HMI interfaces by dragging and dropping components like text, buttons, sliders, and images, while implementing functionality through simple ASCII-based instructions. Communication with a peripheral MCU is achieved via TTL Serial (5V, TX, RX, GND), allowing the display to send event notifications and receive status updates or commands.
The Intelligent Series offers enhanced hardware capabilities—including a more powerful MCU, increased Flash storage, and larger SRAM—compared to the Basic and Enhanced Series. New features like audio, video playback, and animations greatly enrich user interaction. It also supports advanced interface functions such as transparent components, page transition effects, and movable or draggable elements.
Developing with the free Nextion Editor (version 0.58 or later) streamlines the entire process, significantly reducing HMI project development time and effort.
