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.

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 single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
