Here's some information about this type of LED ring:

WS2812 Protocol: The WS2812 protocol, also known as Neopixel, is a popular protocol used for individually addressable RGB LED modules. Each LED in the ring can be controlled independently, allowing you to create complex and dynamic lighting patterns.

5050 Package: The "5050" designation refers to the package size of the LEDs. In this case, it indicates that the LEDs are in a 5.0mm x 5.0mm package. This is a common package size for RGB LEDs, known for its brightness and ease of handling.

RGB LEDs: The ring consists of RGB (Red, Green, Blue) LEDs, which means each LED can emit a wide range of colors. By adjusting the intensity of each color channel, you can create virtually any color in the RGB spectrum.

7-Bit: The "7-bit" description likely refers to the bit depth used to control the LEDs. In this context, it may mean that each color channel (R, G, B) can be controlled with 7 bits of data, allowing for 128 levels of intensity for each channel (0-127).

11.5mm Diameter: The "11.5mm" measurement indicates the diameter of the LED ring. This measurement is important if you need to know the physical size of the ring for your project.

Addressable: Each LED in the ring has its own address, which means you can control each LED independently. This allows for dynamic and animated lighting effects.

Chainable: These LED rings are often chainable, meaning you can connect multiple rings together to create longer strings of LEDs. This can be useful for larger lighting projects.

Control: To control these LEDs, you'll typically need a microcontroller or LED controller that supports the WS2812 protocol. Common microcontrollers used for this purpose include Arduino and Raspberry Pi.

Power Requirements: RGB LEDs can consume varying amounts of power depending on their brightness and the number of LEDs in the ring. You'll need to provide an appropriate power source to ensure they operate correctly.
