About this product
A 5 mm RGB LED with red, green and blue dies and a common cathode, so it has four legs. Each colour can be driven separately, or with PWM to mix colours, which makes it suitable for status indicators and simple lighting effects. The longest pin is the common cathode.

How do I wire a common cathode RGB LED?
Connect the longest pin (common cathode) to GND. Connect each colour pin to its own current-limiting resistor and then to a microcontroller output pin.
Why do the resistor values differ for each colour?
The forward voltages differ: the red die is specified at 2.0 V while the green and blue dies are at 3.2 V. Calculate the resistor for each colour separately so the currents and brightness are balanced.
