The Gravity I2C LCD1602 is a 16×2 character LCD display module from DFRobot's Gravity series, redesigned with a clean modern look and simplified I2C interface. It eliminates the need for contrast adjustment, retains backlight control, and is compatible with both 3.3 V and 5 V systems — making it a plug-and-play display for Arduino and other microcontroller projects.
Using I2C communication, the module requires just two data lines (SDA and SCL) plus power, freeing up GPIO pins for other components. The gray backlight gives a subtle, professional look compared to traditional green LCD modules.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- 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.
- 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.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
