Description
The KY-016 RGB LED Module is a vibrant full-colour LED module that allows you to display a wide range of colours in Arduino, Raspberry Pi, and microcontroller projects.
It features a common cathode RGB LED that can be controlled via PWM (Pulse Width Modulation) to mix red, green, and blue light—allowing you to create millions of colour combinations with simple code.
This module is ideally suited for applications like status lights, mood lighting, visual indicators, or decorative lighting, and is a great way to explore colour mixing and PWM techniques in electronics.
The compact size and 4-pin interface make it easy to integrate into breadboard circuits or permanent project builds.
