Light Disc with 7 SMD RGB LED

The Light Disc with 7 SMD RGB LED is a compact circular illumination module designed for creative lighting and embedded electronics projects. Operating at 5V with integrated current-limiting resistors, it provides smooth colour mixing and up to 6000 mcd brightness via independent PWM channels. It is well suited for makers, students, and hobbyists building interactive lamps, visual indicators, or sensor-driven displays.

Seven-LED array for uniform blending

Seven surface-mount RGB LEDs are arranged on a single circular board to deliver smooth, evenly distributed colour mixing. With a luminous intensity of up to 6000 mcd, the module provides bright visual feedback and ambient illumination across a wide coverage area.

Independent PWM colour control

Independent control pins for the red, green, and blue channels allow duty-cycle adjustment using pulse-width modulation. This enables full-spectrum colour generation, dynamic gradients, and custom reactive lighting effects across your microcontroller projects.

Direct 5V operation with onboard resistors

Integrated current-limiting resistors allow the board to connect directly to standard 5V digital outputs without requiring external components. This simplifies wiring and enhances reliability in USB-powered builds and rapid prototyping setups.

Custom mood and music lighting

When paired with microcontrollers and external sensors under a diffuser or glass cover, the disc can function as a music-responsive lamp or ambient mood light. It creates dynamic lighting driven directly by sound, motion, or environmental data.

Versatile project applications

The compact circular form factor makes this module ideal for decorative enclosures, interactive art installations, and educational electronics. It serves effectively as a high-visibility status indicator or miniature colour panel.

Package contents

Each pack includes one Light Disc with 7 SMD RGB LED module ready for integration with 5V microcontrollers.
