16×02 LCD display module with an IIC I2C interface

The 16×2 LCD Display Module with IIC/I²C Interface is a convenient and easy-to-use character display that shows 16 characters per line on 2 lines. By using the I²C serial interface, it reduces the number of required GPIO pins to just two (SDA and SCL), simplifying wiring and saving microcontroller resources.

This module is compatible with HD44780-based LCDs and comes with an onboard PCF8574 I²C I/O expander, allowing easy integration with Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and other microcontroller platforms. It is ideal for displaying sensor readings, system status, menus, and messages in embedded and IoT projects.

The module supports adjustable contrast and backlight control, ensuring clear visibility in various lighting conditions. Its compact design and low power consumption make it perfect for DIY electronics, educational projects, and industrial applications.
