An SMD (surface-mount device) 3 Color LED Module is an electronic component that contains three separate LEDs (Light Emitting Diodes) in a surface-mount package. Each of these LEDs emits light in a different color: typically red, green, and blue (RGB). These three colors can be combined in various ways to create a wide range of colors using a technique called color mixing.

Here are some key characteristics and features of an SMD 3 Color LED Module:

RGB LED: As mentioned earlier, the module includes red, green, and blue LEDs, which are the primary colors of light. By adjusting the brightness of each LED, you can create different colors, including white, by mixing these primary colors.

Surface Mount: The term "SMD" indicates that these LEDs are designed for surface-mount technology, which means they can be directly soldered onto the surface of a printed circuit board (PCB) without the need for through-hole components or leads.

Control: These modules are often used in conjunction with microcontrollers or other control systems to achieve precise control over the color and intensity of the emitted light. PWM (Pulse Width Modulation) is commonly used to control the LEDs' brightness.

Applications for SMD 3 Color LED Modules are numerous and include:

Decorative Lighting: They are used in decorative lighting applications, such as LED strips, to create colorful and dynamic lighting effects.

Display Panels: They are used in display panels and screens to produce a wide range of colors for images and videos.

Indicator Lights: In electronics, they are used as indicator lights to convey information or status.

Signage: They are used in outdoor and indoor signage to display vibrant and attention-grabbing messages.

Entertainment: In entertainment and stage lighting, these modules are used to create captivating light shows and effects.

    Not what I thought but good.

    Took a star off because I think they're trying to be A little deceptive in my opinion. I've was wondering why the pictures are black and white. And in my opinion, its to hide the 3 prongs. I thought these are this smart chips that turn regular rgb led into addressable ones like adafruit makes. Dont know what illusion these fir but ill find something. They feel and look like good quality.

    All of the 10 LED works

    We purchased them for an engineer project for kids, I am glad all of them works!
