Nextion NX4832T035 3.5″ HMI TFT LCD TOUCH Display module

Description

Product Overview

The Nextion Basic NX4832T035 is a powerful, intelligent Human-Machine Interface (HMI) display module that combines a 3.5-inch TFT LCD color screen with a resistive touch panel into a single, easy-to-use package . Designed to provide a seamless control and visualization interface, this Basic series display is the ideal solution for IoT applications, consumer electronics, industrial automation, and embedded projects.

What sets the Nextion apart from traditional LCDs is its intelligent architecture. Unlike standard displays that require your main microcontroller to handle all graphics rendering, the NX4832T035 features a dedicated onboard processor (running at 48MHz) that independently manages all graphical interface functions—drawing buttons, updating text, displaying graphs, processing touch inputs, and managing screen transitions . Your host microcontroller (Arduino, ESP32, Raspberry Pi, STM32) communicates with the display using simple ASCII text commands over a standard UART (TTL serial) interface . This approach eliminates the need for complex graphics programming and parallel wiring, dramatically reducing development time.

The free, drag-and-drop Nextion Editor software allows you to design your graphical user interface visually without writing a single line of graphics code. Simply place components onto the canvas, assign properties, and compile . The WYSIWYG environment reduces GUI development workload by up to 99% compared to traditional methods.

Each package includes a power supply test board that allows you to verify your power supply can deliver enough current before connecting the display, preventing damage from insufficient power .

Key Features

• 3.5-Inch TFT LCD Display: 480 × 320 pixel resolution (also configurable as 320×480) with 65,536 colors (16-bit RGB 565), providing vivid, true-to-life visuals

• Resistive Touch Panel: Durable 4-wire resistive touch screen rated for over 1 million touches; responds to finger, gloved hand, or stylus input

• Intelligent Standalone Operation: Onboard 48MHz MCU handles all graphics and touch processing independently—your host MCU only needs to send simple commands

• Simple Serial Communication: 4-pin UART interface (VCC, GND, TX, RX) using TTL 3.3V/5V tolerant logic—connects directly to Arduino, ESP32, Raspberry Pi, or STM32

• Free WYSIWYG GUI Editor: Nextion Editor software with 25+ drag-and-drop components (buttons, text boxes, sliders, progress bars, gauges, timers) and built-in simulator for debugging without hardware

• Adjustable LED Backlight: Brightness adjustable from 0% to 180 nits in 1% increments via simple serial command

• Built-in Flash Storage: 16MB flash memory for storing fonts, images, and HMI program data; 3584 bytes RAM for variables

• microSD Card Slot: For easy firmware updates (TFT file upload). Supports FAT32 format, up to 32GB

• Wide Operating Voltage Range: Accepts 4.75V to 7.0V DC (5V typical), with operating current of 145mA (normal) and 15mA (sleep mode)
