Product Overview
The RGB LED Module features a single multi-color RGB LED capable of producing a wide range of colors by mixing Red, Green, and Blue channels. Each color channel is connected through an onboard current-limiting resistor, making it safe and easy to interface with microcontrollers and FPGA boards.
 
With independent control of all three colors, this module is perfect for color indication, lighting effects, and PWM-based applications.

Working Principle
The LED uses a common cathode, meaning:
GND is shared across all colors
Applying HIGH signal to R/G/B pins turns ON respective color
By combining signals:
R + G → Yellow
R + B → Magenta
G + B → Cyan
R + G + B → White
Using PWM (Pulse Width Modulation):
You can generate millions of colors by varying brightness of each channel
 
Notes:
Ensure correct polarity when supplying voltage
Avoid exceeding recommended voltage for long-term use. 
For long-term use, keep the voltage within 3.3V/5V range.
