![]() Now you all might be thinking that there are only 3 LEDs in this, and we can have only 3 colors RED, GREEN, and BLUE. While in common anode SMD RGB LED, common terminal is connected with +Ve supply and R, G or B terminal has to be connected to ground. It is understood that to turn on any LED in common cathode type RGB SMD LED, we have to apply +Ve supply to R, B, or G terminal, and the common terminal is connected to the ground. Please have a look at the figure given below. This common terminal can be either anode or cathode, and based on it, there are two types of such LEDs (1) common cathode and (2) common anode. Three terminals are for RED (2), GREEN (4), and BLUE (6) LEDs, while the other 3 terminals are common terminals.
