This module is made of a 10 mm diffused RGB LED with the necessary current limiting resistors and 4 right-angle pins, one for each primary colour and another one for ground. This module can be plugged directly to a breadboard. You can light up each of the three primary colour by applying voltage to the corresponding pin or you can produce a variety of changing mixed colour by applying PWM voltage to the pins creating a colour transition effect. This module runs on 5V or 3.3V and suitable to be controlled by Arduino and other development boards.
