WS2812B Neopixel Addressable RGB Led Module 2x2 Square Matrix 4-bit

The WS2812 LED matrix or LED ring is a versatile and popular lighting component that comprises multiple individually addressable RGB (Red, Green, Blue) LEDs integrated into a single circuit. It is commonly used in a variety of creative and decorative applications, including mood lighting, visual effects, signage, and more.

Key Features:

• LED Configuration: The WS2812 LED matrix or LED ring typically consists of a series of RGB LEDs arranged in a specific pattern, such as a grid (for a matrix) or a circle (for a ring). Each LED has three individually controllable channels for red, green, and blue colours, enabling a wide range of colour combinations.
• Individually Addressable: One of the standout features of WS2812 LEDs is their individually addressable nature. Each LED in the matrix or ring can be controlled independently, making it possible to create dynamic lighting patterns, animations, and effects.
• Daisy-Chaining: You can link multiple LED matrices or rings in a chain and control them all with a single data line.
• Digital Control: The WS2812 LEDs use a digital control protocol, based on the WS2812 or NeoPixel protocol. This protocol enables you to control the color and brightness of each LED by sending specific digital commands to the LEDs. Microcontrollers like Arduino and Raspberry Pi are commonly used for this purpose.
