These NeoPixels 1/4 ring comes with 15 individually addressable LEDs each containing 4 differnet colours (red, green, blue and white) for producing excellent lighting effects. This particular version of NeoPixel 1/4 60 LED Ring is in Cool White.

With four of these you can make a huge ring with 60 ultra bright smart LED NeoPixels are arranged in a circle with a 6.2" diameter. Each order comes with just the quarter ring. Four of this item are required to make a large ring and they do need to be soldered together.

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 5VDC.

The NeoPixel is 'split', one half is the RGB, the other half is a white LED with a yellow phosphor. Unlit, it resembles an egg yolk. Lit up these are extremely bright and can be controlled with 8-bit PWM per channel (8 x 4 channels = 32-bit color overall). Great for adding lots of colourful + white dots to your project!

NeoPixel LEDs use 800 KHz protocol so specific timing is required. On NeoPixels, the PWM rate is ~400 Hz, which can be noticeable if the LED is moving. NeoPixels are 5050-sized LEDs with an embedded microcontroller inside the LED. You can set the brightness and colour of each R/G/B/W with 8-bit PWM precision (so 32-bit color per pixel). The LEDs are controlled by shift-registers and only 1 digital output pin are required to send data down. The PWM is built into each LED-chip so once you set the colour you can stop talking to the ring and it will continue to PWM all the LEDs for you.

Note: When soldering these 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.
