Gravity: Digital LED String Lights (Colorful, 4m, 40 LEDs)

The Gravity Digital LED String Lights feature 40 colourful LEDs spaced across a 4-metre cable. Designed for quick integration with microcontroller platforms, it suits students, hobbyists, and makers creating interactive installations or embedded lighting projects.

Four-metre length with 40 LEDs

The module includes 40 colourful LEDs distributed evenly along a 4-metre flexible cable. This length provides plenty of span for decorating models, props, or physical computing displays.

Wide 2.5V to 5V voltage support

Operating across a voltage range of 2.5V to 5V, this LED string is compatible with common 3.3V and 5V logic microcontrollers. It powers efficiently without needing dedicated high-voltage drivers.

Standard Gravity digital interface

The light string connects directly using the standard Gravity digital pinout for clean and plug-and-play wiring. It allows straightforward digital on/off switching and software-driven lighting effects.

Interactive and embedded applications

Designed for embedded projects, the string adds visual feedback and illumination to robotics, smart home prototypes, and art installations. Its low-voltage profile makes it suitable for classroom and hobbyist experiments.
