HKD KY-009 RGB LED Module 5V Arduino Compatible SMD 5050 Full Color Light

Create stunning color-changing lighting effects with this professional RGB LED module. Perfect for Arduino projects, mood lighting, indicators, and decorative applications. Mix millions of colors using simple PWM control.

Key Features

Professional 5050 SMD RGB LEDHigh-brightness 5050 surface-mount LED provides vibrant, uniform color mixing with excellent light output and long lifespan.

Full Color Spectrum ControlMix red, green, and blue channels using PWM signals to create millions of different colors - from subtle pastels to brilliant saturated hues.

Arduino Ready DesignPerfect for beginners and professionals alike. Simple 4-pin interface connects directly to Arduino digital pins for instant color control.

Built-in ProtectionIntegrated current limiting resistors on each color channel prevent LED burnout and eliminate the need for external resistors.

5V OperationStandard 5V operating voltage works directly with Arduino Uno, Nano, ESP32, Raspberry Pi, and most microcontroller boards.

How It Works

PWM Color MixingEach color channel (Red, Green, Blue) accepts a PWM signal from 0-255 (or 0V-5V). By varying the intensity of each channel, you can create any color:

• Red only: Pure red light
• Green + Blue: Cyan colors
• Red + Green: Yellow/orange colors
• Red + Green + Blue: White or any mixed color

Simple 4-Pin Connection

• VCC: Connect to 5V power supply
• R: Red channel control (connect to digital pin)
• G: Green channel control (connect to digital pin)
• B: Blue channel control (connect to digital pin)
