Description NeoPixel 1/4 60 Ring - 5050 RGBW LEDs - Natural White ~4500K
This is the 1/4 RGBW NeoPixel Ring from Adafruit. It contains 15 RGBW (red, green, blue, white) LED lights. With 4 of these segments you can make a large (157mm) LED ring with 60 NeoPixels.
Each LED can be controlled separately. This allows you to create excellent lighting effects and LED projects. This version comes with a natural white RGBW version.
The NeoPixel is split, one half is the RGB and the other half is a white LED. Per board are 15 of the small 5050 (5x5mm) smart RGBW LEDs. To make a complete ring you will need 4 boards have to solder together.
you can do so much boards if you want to connect yourself. This while using only one microcontroller pin. Each LED is individually addressable because the driver chip is inside the LED. They each have ~18mA constant current drive so that the color remains very consistent. This even when the voltage varies. No external choke resistors are needed, keeping the design sleek. Provide the whole with 5VDC and you are ready to go.
NeoPixel LEDs use a 800kHz protocol, so specific timing is required. On NeoPixels the PWM speed is ~400Hz, this works well but is noticeable when the LED moves.
Since the protocol is very sensitive to timing, a real-time microcontroller is needed, such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the NetDuino. Adafruit has a NeoPixel library for Arduino which makes it easy to use. An 8MHz or faster processor is required. On the Adafruit's site are tutorials with wiring available.
