SMD 3-Colour RGB LED Module – High-Brightness Full-Colour Light Module for Arduino, Raspberry Pi, and ESP32 Robotics and Decorative Lighting Projects

Product Description

Bring a spectrum of light to your projects with the SMD 3-Color RGB LED Module. This compact breakout board features a high-intensity 5050 SMD LED capable of producing almost any color by mixing Red, Green, and Blue light at varying intensities. At Robogears, we recommend this module for status indicators, decorative ambient lighting, and color-coding robotic behaviors. Unlike standard through-hole LEDs, the SMD 5050 provides a wider viewing angle and a more uniform color blend. Whether you are building a mood lamp or a multi-state alarm system at your Pimpri workshop, this breadboard-friendly module offers an easy way to integrate full-color illumination without complex wiring.

Detailed Key Features

• Full-Color Spectrum: By using PWM (Pulse Width Modulation), you can control the brightness of each internal LED to create millions of custom colors.

• Integrated Current Limiting: (Note: Most variants include small SMD resistors; if not, external 220-ohm resistors are required to protect the LED).

• Common Cathode Design: The negative terminal is shared, making it simple to control the R, G, and B pins using the digital/PWM output pins of your microcontroller.

• Ultra-Compact Footprint: The tiny SMD LED is mounted on a rigid PCB with pre-soldered headers, perfect for tight spaces in robotic chassis.

• Plug-and-Play Compatibility: Works seamlessly with all 3.3V and 5V logic systems, including Arduino, ESP8266, and STM32.

All Technical Details

• Pin Definition:

  • R: Red Light Control.

  • G: Green Light Control.

  • B: Blue Light Control.

  • - (GND): Common Negative (Cathode).

• PWM Support: Required for color mixing (e.g., 50% Red + 50% Blue = Purple).

• Applications: Notification lights, light-up wearable tech, toy electronics, and scientific color-mixing experiments.
