The Gravity I2C LCD1602 is a 16×2 character LCD display module with a blue backlight and white text. It communicates over I2C, requiring only two data pins instead of the many parallel connections of a traditional LCD1602. The module is compatible with both 3.3V and 5V systems, and the contrast is pre-set so no manual adjustment is needed.
The Gravity connector interface makes it easy to plug into DFRobot expansion shields and other Gravity-compatible boards without soldering. The backlight can be controlled in software.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
