The LED RGB – 4-Pin – 5mm (Common Cathode) is a compact, through-hole tricolor LED capable of producing red, green, blue, and mixed colors by controlling individual LED channels. With a common cathode configuration, all negative terminals are internally connected, making it easy to interface with microcontrollers and logic circuits.
This LED is ideal for Arduino projects, robotics, indicators, learning experiments, and DIY electronics, allowing users to create multiple colors through PWM or simple digital control.
