Full Color RGB LED Module 4-Pin (KY-016)

The Full Color RGB LED Module 4-Pin (KY-016) is a compact breakout board built around a clear 5mm RGB LED, giving makers an easy way to mix red, green, and blue light channels for custom color effects. Its onboard current-limiting resistors mean the LED can be driven straight from a microcontroller’s PWM pins without any extra components.

Key features:

• Full Color LED: Features a clear 5mm RGB LED capable of producing a wide range of colors by mixing red, green, and blue intensities.
• Onboard Resistors: Includes current-limiting resistors for each color channel, so the module connects directly to digital or PWM outputs.
• Common Cathode Wiring: Uses a shared cathode pin alongside separate R, G, and B pins for simple four-wire hookup.
• PWM Compatible: Works with analogWrite()-style PWM control to fade and blend colors smoothly.
• Compact Footprint: Small PCB with mounting holes, easy to fit into breadboards or enclosures.
• Beginner Friendly: A popular first project for learning PWM, color mixing, and basic output control.

This module is a favorite for mood lighting projects, status indicators, and color-mixing demonstrations, and it drops straight into any 5V Arduino, ESP8266, or ESP32 project without additional drivers.
