Nextion NX3224F028 – 2.8" Discovery Series Smart HMI Touch Display
The Nextion NX3224F028 is a 2.8-inch resistive touchscreen display from the Discovery Series—an affordable and efficient SMART HMI solution. Powered by a 64MHz STM32GO ARM Cortex-M0+ onboard processor, it offers up to 30% better performance than the Basic Series. With its Deep Sleep Mode consuming as little as 0.25 mA, it’s perfect for battery-powered applications requiring extended uptime.
This HMI display communicates via a single UART (TX, RX, GND, 5V), making integration with platforms like Arduino, Raspberry Pi, ESP8266/ESP32, PIC, AVR, ARM—even 8051 microcontrollers—extremely simple. If your device has a UART port, it’s ready for Nextion.
The solution combines hardware and the powerful Nextion Editor software. The Editor features an intuitive drag-and-drop interface and a wide array of built-in GUI components—such as buttons, sliders, text fields, progress bars, and instrument panels—minimizing coding effort and drastically cutting development time.
With low power usage, broad compatibility, and an easy development environment, the NX3224F028 makes sophisticated HMI design accessible and practical for any embedded project.
