LED RGB WS2812B or WS2812 Ring 5050 with Integrated Drivers

compatible with NeoPixel Adafruit libraries

Ultra bright smart LED are arranged in a circle.

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 colour 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 5V DC and you're ready to rock.

Every ring is equipped with a single data line with a very timing-specific protocol requiring a real-time micro-controller with a 8MHz or faster processor such as an AVR, Arduino, PIC, Raspberry etc.

There are solder pads on the back for connecting wires or breadboard pins and two mounting holes for securing this board to many different surfaces.

Please note:

60 LED Ring consists of four sections - When soldering the sections together, line up the four pieces and connect all the GND and 5V pins together as shown above. Then for three out of the four pieces solder DIN to DOUT. The remaining DIN is the input pin for the entire ring.

These Rings are not Adafruit products. 'NeoPixel' and 'Adafruit' are registered trademarks of Limor Fried
