Description
The KY-011 Bi-Colour LED Module features a red/green dual-colour LED that’s ideal for simple visual indicators in Arduino, Raspberry Pi, or other microcontroller-based projects.
This compact module includes a common cathode dual LED, allowing you to light either red, green, or a combination of both (to create an amber/orange hue) depending on your project’s needs.
This module is ideally suited for applications such as status indicators, signal lights, traffic light simulations, and simple user feedback systems.
Thanks to its small size and 3-pin interface, it’s perfect for breadboard prototyping or integration into compact electronic builds.
