This is an 16x2 LCD display screen with with I2C interface. It is able to display 16x2 characters on 2 lines, white characters on blue background.
Usually, Arduino LCD display projects will run out of pin resourceseasily, especially with Arduino Uno. And it is also very complicated with the wire soldering and connection.
This I2C16x2 Arduino LCD Screen is using an I2C communication interface. It means it only needs 4 pins for the LCD display: VCC, GND, SDA, SCL. It will saves at least 4 digital / analog pins on Arduino. All connector are standard XH2.54 (Breadboard type). You can connect with jumper wire directly.
To avoid the confliction of I2C address with other I2C devices, such ultrasonic sensor, IMU, accelerometers and gyroscope, the I2C address of the module is configurable from 0x20-0x27. And its contrast can be adjusted manually.
Another alternative option is I2C 20x4 Arduino LCD Display Module if more characters is required.

Jargon buster
Plain-language definitions for the technical terms used above.
- Gyroscope
- A gyroscope measures rotation, such as how fast a board is turning around its X, Y, and Z axes. This matters for projects like gesture controls, balancing robots, and motion tracking where tilt or rotation changes need to be detected.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- I2C address
- An I2C address is the number a device uses so a microcontroller can tell it apart from other devices on the same I2C bus. It matters because two devices with the same fixed address may conflict if used together.
- IMU
- An Inertial Measurement Unit combines motion sensors to measure movement and orientation. It matters for asset tracking because it can detect movement, tilt, vibration, or changes in direction.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
