Frequently Asked Questions

Where can I buy Nextion displays in Europe?

Robotics3D is an official Nextion distributor in Europe. We stock 27+ HMI displays with fast EU shipping from Italy. Orders placed before 2pm ship same day. All displays come with enclosure, cables, and documentation.

What is the difference between Nextion Basic, Enhanced, and Intelligent series?

Basic series has resistive touch and serial communication (best for hobby projects). Enhanced adds capacitive touch, RTC, GPIO, and audio (recommended for industrial use). Intelligent series includes video playback and file operations for complex HMIs with data logging. All use the same Nextion Editor software.

How do I connect a Nextion display to Arduino?

Connect 4 wires: 5V power, GND, TX to Arduino RX, RX to Arduino TX. Use SoftwareSerial on pins 2/3 for Arduino Uno, or hardware Serial1/Serial2 on Mega. Set baud rate to 9600 (default). Upload .tft file to Nextion using microSD card or serial upload. We provide example Arduino sketches.

Can I design custom UIs for Nextion displays?

Yes! Use the free Nextion Editor software (Windows/Mac). Drag-and-drop interface builder with 30+ component types (buttons, sliders, gauges, graphs). Import custom images and fonts. No graphics programming required. Export .tft file and upload to display via microSD card.

What programming languages work with Nextion?

Nextion uses simple ASCII serial commands that work with any language. Popular options: Arduino C++, MicroPython, CircuitPython, Python (Raspberry Pi), C#, Visual Basic, LabVIEW. Community libraries available for most platforms. Send commands like "page 0" or "t0.txt=Hello".

What sizes are Nextion displays available in?

Sizes range from 2.4" (320x240) to 10.1" (1024x600). Most popular: 3.5" (480x320), 5.0" (800x480), 7.0" (800x480, 1024x600). All include both portrait and landscape mounting holes. Some models available with or without enclosure.
