KY-016 RGB LED Module 5mm 3 Color

The KY-016 RGB LED Module is a compact, easy-to-use full-color LED breakout board designed for Arduino, ESP32, Raspberry Pi, and other popular microcontroller platforms. Built around a common-cathode 5mm RGB LED, this module allows you to mix red, green, and blue light channels independently to produce virtually any color in the spectrum — making it perfect for status indicators, mood lighting, visual feedback systems, and creative electronics projects.

Ideal for students, hobbyists, and makers, the KY-016 requires no additional components — simply connect it to three PWM-capable digital pins and a ground, and you’re ready to start experimenting. Its standard 4-pin header ensures breadboard and jumper wire compatibility, and its lightweight design fits neatly into any project enclosure.

Whether you’re building a notification light, an interactive display, or learning about PWM color mixing, the KY-016 delivers vibrant, consistent color output in a plug-and-play format.
