This is the NeoPixel 1/4 60 LED Ring in natural white. These NeoPixels now have 4 LEDs in them (red, green, blue and white) for excellent lighting effects.

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 the quarter ring. Four of this item are required to make a large ring and need to be soldered together. Each quarter ring of 15 x individually addressable RGB LEDs comes assembled and tested. We recommend you buy four to build the full circle as this is just the 1/4 of the 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 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.

The NeoPixel is 'split', one half is the RGB you know and love, the other half is a white LED with a yellow phosphor. Unlit, it resembles an egg yolk. Lit up these are insanely bright and can be controlled with 8-bit PWM per channel (8 x 4 channels = 32-bit color overall). Great for adding lots of coloured + 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 works well but is noticable if the LED is moving. In comparison, DotStars have a 20 KHz PWM rate, so even when moving the LED around, you won't see the pixelation, the blending is very smooth.

NeoPixels are 5050-sized LEDs with an embedded microcontroller inside the LED. You can set the brightness and color 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 color 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. Then for three out of the four pieces solder DIN to DOUT. The remaining DIN is the input pin for the entire ring.
