16×2 LCD Display with I2C Interface – Yellow-Green Backlight

Simplify your wiring and give your project a retro-industrial look with the Yellow-Green 16×2 LCD Display with I2C Interface. While standard LCDs demand a mess of wires, this pre-soldered module uses a PCF8574 I2C Backpack, reducing connection requirements to just 2 wires (SDA and SCL) plus power.

High Visibility

This model features the classic Yellow-Green Backlight with Black Text. It is widely preferred for outdoor applications and industrial projects because the black characters are easy to read even in high-glare situations.

Efficient & Easy to Use

The I2C protocol allows you to daisy-chain multiple devices on the same bus. With the built-in library support for Arduino (LiquidCrystal_I2C), you can get text on the screen in minutes without worrying about complex 4-bit or 8-bit addressing.

Key Features

• Simplified Wiring: Connects via I2C, freeing up valuable digital pins on your board.

• Classic Look: 16 characters x 2 lines with Black text on a bright Yellow-Green background.

• Adjustable Contrast: Features a blue potentiometer on the back to adjust text visibility.

• Ready to Use: I2C backpack comes pre-soldered, no extra assembly required.

• Versatile Power: Runs on standard 5V logic.

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.
