The Nextion NX8048T050 5-Inch HMI TFT LCD Touchscreen Display is a smart Human-Machine Interface (HMI) module designed for creating interactive graphical control panels for embedded systems, industrial automation, robotics, and IoT applications.
Part of the Nextion Basic Series, the NX8048T050 features a 5-inch TFT LCD with 800 × 480 pixel resolution, 65,536 colors, and a resistive touchscreen for user interaction.
Unlike conventional LCD displays that require the microcontroller to handle graphics rendering, Nextion displays feature an onboard processor that manages the graphical interface independently. This reduces the workload on the main microcontroller and simplifies system development.
Using the free Nextion Editor software, developers can design graphical interfaces with buttons, sliders, text fields, progress bars, gauges, images, and other interactive components.
The display communicates with external controllers through a TTL UART serial interface, making it suitable for Arduino, ESP32, STM32, Raspberry Pi, and other embedded development platforms.

Important: The Nextion display uses TTL UART communication. The host controller and display must share a common ground.
For Arduino UNO, using a suitable software serial interface can avoid conflicts with USB programming.
For ESP32 and Raspberry Pi, ensure the UART signal voltage levels are compatible. Use appropriate level shifting when necessary.
Nextion Editor Software
The NX8048T050 is programmed using Nextion Editor, a graphical development environment for creating custom touchscreen interfaces.
