I2C BOARD MODULE

I2C LCD Interface Module

The I2C LCD Module allows you to connect character LCDs (like 16×2 or 20×4) to your microcontroller using just 2 wires (SDA & SCL), saving valuable I/O pins on boards like Arduino, ESP32, or Raspberry Pi.

Key Features:

• Based on PCF8574 I/O expander

• Converts standard LCD to I2C interface

• Adjustable contrast via onboard potentiometer

• Includes backlight control

• Operating Voltage: 5V

• Compatible with most 16×2 and 20×4 LCDs

Applications:

• Arduino LCD projects

• DIY electronics and automation

• Projects with limited GPIO availability

• Educational and display systems
