The RGB LED Module SMD 5050 KY-009 is a board designed to facilitate the implementation of small projects using an RGB LED. This module consists of an SMD RGB 5050 LED and already has the connection terminals that are identified.
The RGB LED can display a large number of colors that originate from three primary colors. The 5050 SMD is a 'tri' chip, meaning it has three smaller chips in every SMD. So each white LED has three white chips inside. 5050s can also be used for color-changing LED tape, with red, green, and blue chips inside each LED.
Each LED represents a different color: red (R), green (G), and blue (B). Each of these LEDs can be individually controlled, and if combined, they can generate different colors.
