The Nextion NX4827P043_11 is a 4.3-inch intelligent display module designed to simplify the process of adding a graphical user interface (GUI) to your electronic projects. This display device integrates a TFT touchscreen, a microcontroller, and a graphical interface editor, making it an all-in-one solution for visually presenting information, images, or video output from a computer or electronic device.
Common applications for the Nextion NX4827P043_11 include:
This circuit is a quiz game system using an Arduino UNO, an I2C LCD 16x2 screen, and three pushbuttons. The Arduino controls the LCD to display questions and receives input from the pushbuttons to check answers and restart the quiz.
Open Project in Cirkit Designer
This circuit is designed to monitor environmental parameters and display information on an I2C LCD screen. It uses an ESP-8266 microcontroller to interface with a DHT11 temperature and humidity sensor, an MQ-4 methane gas sensor, an HC-SR04 ultrasonic distance sensor, and an HC-SR501 motion sensor. The ESP-8266 collects data from these sensors and can display it on the LCD or use it for other processing as defined in the embedded code.

This circuit features an Arduino UNO connected to a 16x2 LCD display for text output. The Arduino controls the display via digital pins D2 to D5 for data transmission and pins D11 and D12 for enable and register select signals. A trimmer potentiometer adjusts the display contrast, and a resistor provides current limiting for the LCD backlight.

| 3 | TX | UART Transmit (data sent from the display) |
| 4 | RX | UART Receive (data sent to the display) |
Below is an example of how to interface the Nextion NX4827P043_11 with an Arduino UNO:
#include <SoftwareSerial.h>
// Define RX and TX pins for SoftwareSerial
SoftwareSerial nextion(10, 11); // RX = Pin 10, TX = Pin 11
void setup() {
// Initialize serial communication with Nextion display
nextion.begin(9600); // Set baud rate to 9600
Serial.begin(9600); // For debugging via Serial Monitor
// Send a command to the Nextion display
nextion.print("page 0"); // Switch to page 0 on the display
nextion.write(0xFF); // End of command
nextion.write(0xFF); // End of command
nextion.write(0xFF); // End of command
}
void loop() {
// Example: Send a text update to a component on the display
nextion.print("t0.txt=\"Hello, World!\""); // Update text field t0
nextion.write(0xFF); // End of command
nextion.write(0xFF); // End of command
nextion.write(0xFF); // End of command
delay(1000); // Wait for 1 second
}

Q: Can I use the Nextion NX4827P043_11 with a Raspberry Pi?
A: Yes, the display can be connected to a Raspberry Pi via UART. Ensure proper voltage level shifting if required.
Q: How do I update the firmware or GUI on the display?
A: Use a microSD card to upload the firmware or GUI files generated by the Nextion Editor. Insert the card into the display and power it on to start the update process.
Q: What is the maximum cable length for UART communication?
A: For reliable communication, keep the cable length under 1 meter. Use shielded cables for longer distances.
Q: Can I use multiple Nextion displays in one project?
A: Yes, but each display must be connected to a separate UART port or controlled via a multiplexer.
