An 8-digit green LED segment display module with I2C communication, part of the DFRobot Gravity sensor and module range. It provides a clear, bright numerical display with 16 levels of adjustable brightness, making it easy to show sensor readings, counters, clocks, and other numerical data in your projects.
The Gravity I2C interface keeps wiring simple — just connect power, ground, SDA, and SCL to your Arduino or other microcontroller. The module supports the full 8-segment × 8-digit display format for showing numbers, basic characters, and decimal points.

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.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- 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.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
