Gravity: Digital RGB LED Module is a cascadable single RGB LED module compatible with RGB LED strip. The Gravity interface provides a more elegant manner for the connections between modules and most of mainstream controllers such as Arduino, micro:bit, Firebeetle Series, LattePanda, and Raspberry Pi with an abundant kinds of DFRobot IO expansion shield. Compared to the traditional RGB LED module, where three control signal pins are required for a single LED, this module only needs one signal pin for all LEDs in cascade. Thanks to such individual module design, RGB LED strip built by such independent modules can realize extremely low power consumption per meter compared to traditional RGB LED strip. And such feature makes it possible to cascade more than 100 modules with a total length up to several tens of meters but power requirement no more than 5V 2A. This also makes it much simpler and more flexible to configure the length of an RGB LED strip, without the need of cutting a RGB LED strip or soldering every LED piece.
The module adopts the same high-brightness RGB LED in the traditional RGB LED strip, inheriting its excellent display performance and is fully compatible with the driving circuit or program. This requires little changes for existing programs to shift from RGB LED strip to RGB LED module string. Have fun with this tiny RGB LED module by cool effects of flashing, rainbow, even letters, pictures or animations.

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.
- 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.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
