20×4 Character Backlit LCD Display with I2C Interface High-Visibility Display for Arduino & Raspberry Pi Projects

This version of the display replaces the older non-i2c version. This version is significantly easier to wire up and program for that the previous version. It also uses up many less wires and pins on your microcontroller like a Raspberry Pi, ESP or Arduino. This version will save you a huge amount of time and allow you to quickly implement a clear, bright and easy to read information feedback display into your project.

Enhance your microcontroller projects with the 20×4 Character Backlit LCD Display, designed to provide clear, crisp text output while conserving I/O pins through its I2C interface. This blue-backlit, blue-character LCD is perfect for displaying sensor readings, real-time data, and debugging information in your DIY electronics and embedded system applications. Compatible with Arduino, Raspberry Pi, ESP32, ESP8266, and other 3.3V/5V microcontrollers, this module simplifies integration with minimal wiring.

Key Features:

• 20×4 Character Display: Four lines of 20 characters each, ideal for detailed data visualization.
• I2C Interface: Reduces the number of required GPIO pins (only SDA & SCL needed), freeing up microcontroller resources.
• Adjustable Contrast: Built-in potentiometer allows fine-tuning for better readability.
• Blue Backlight with Blue Characters: High contrast for improved visibility in various lighting conditions.
• Wide Compatibility: Works with Arduino, Raspberry Pi, ESP32, ESP8266, STM32, and other microcontrollers.
• Efficient Power Consumption: Runs on 5V supply with low power draw.
• Easy Integration: Uses standard I2C address (0x27 or 0x3F), making it simple to set up with existing libraries.

Technical Specifications:

This 20×4 I2C LCD module is an essential component for any maker or developer looking to add a user-friendly display to their projects while keeping wiring minimal. Whether you’re building a weather station, system monitor, home automation project, or real-time data logger, this display module ensures high readability, simple connectivity, and reliable performance.
