RGB LED Ring WS2812B 5050 - 12 LEDs Ø50mm

Tax included

Round and round and round they go! 12 ultra bright smart LED NeoPixels are arranged in a circle with 1.5" (37mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're ready to rock.

This product is a WS2812B LED Ring with 12 LEDs. There are easily solderable pads on this circuit board for soldering wires.

The color of the LED is controlled by the built-in chip. You can place a lot of these LEDs behind each other and control them digitally with just 1 pin. The LED is usually supplied with the commonly used 5V voltage.

You can place up to 1024 LEDs behind each other and still get 30fps. (30 refreshments per second)
The LED is of the type RGB where each color can be controlled with 8 bits. As a result, each LED can show 16777216 kinds of colors. (24 bits)

Various platforms offer support for this LED with libraries, including Arduino and Raspberry Pi.
More information for the Arduino platform can be found here: WS2812 Breakout Hookup Guide or Adafruit NeoPixel Überguide.
