I2C Module for LCD Display

The I2C module for LCD is a small adapter that lets you connect a 16×2 or 20×4 character LCD to your microcontroller using only two wires. No more messy wiring or confusing pins.

This LCD I2C adapter board uses the I2C communication protocol, making it easy to use with Arduino, Raspberry Pi, ESP32, and more. Whether you’re a student, hobbyist, or pro, this module simplifies your electronics project.

Key Features of the I2C LCD Module

• 2-Wire I2C Interface: Saves up to 6 GPIO pins
• Backlight Control: Switch LCD light on or off via code
• Contrast Adjustment: Built-in potentiometer
• PCF8574 Chip: Stable I2C communication
• Compact Design: Fits neatly behind the LCD
• Easy to Install: Plug-and-play with jumper wires
• Compatible With: 16×2 and 20×4 LCD displays

Why Choose an I2C Interface for LCD?

Using a LCD display I2C adapter cuts wiring from 16 connections to just 4 (VCC, GND, SDA, SCL). This means faster setups, cleaner projects, and fewer errors.

Perfect for:

• DIY Projects
• Student Labs
• Prototyping Circuits
• Arduino-based Interfaces
• Raspberry Pi Projects

Whether you’re monitoring temperature, displaying menus, or building smart devices, this module helps you focus on your project — not the wiring.
