16×2 LCD Display with I2C Interface – Blue Backlight

isplaying data on your Arduino project just got easier and cooler with the Blue 16×2 LCD Display with I2C Interface. Standard LCDs require up to 6 digital pins to function, cluttering your wiring and limiting your sensors. This module solves that problem by integrating a PCF8574 I2C Backpack, allowing you to control the entire screen using just 2 wires (SDA and SCL).

Crisp Visuals

This model features a stunning Blue Backlight with White Text, providing excellent contrast and a modern look for your projects, whether in low light or bright environments.

Smart I2C Connectivity

By using the I2C (Inter-Integrated Circuit) protocol, this display communicates via a specific address (usually 0x27 or 0x3F). This frees up the digital I/O pins on your microcontroller for other important components like motors, sensors, and actuators.

Key Features

• Pin Saver: Uses only 2 I/O pins (SDA & SCL) instead of the standard 6.

• Vivid Display: 16 characters x 2 lines with White text on a deep Blue background.

• Adjustable Contrast: Includes a built-in potentiometer on the back to fine-tune text sharpness.

• Wide Compatibility: Works perfectly with Arduino, Raspberry Pi, ESP32, and STM32.

• Backlight Control: Jumper allows you to turn the backlight on or off programmatically or physically.

Technical Specifications

Typical Application Scenarios

Note

Troubleshooting Tip: If you see only blocks on the top row or no text at all, use a screwdriver to gently turn the potentiometer on the black I2C backpack until the text becomes visible. Also, verify if your I2C address is 0x27 or 0x3F using an I2C scanner sketch.
