The biggest NeoPixel Ring yet! 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. You will have to
solder them together as well, so for the full ring of 60 LEDs, buy
four and solder them 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 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.
There is a single data line with a very timing-specific protocol.
Since the protocol is very sensitive to timing, it requires a
real-time microcontroller such as an AVR, Arduino, PIC, mbed, etc. It
cannot be used with a Linux-based microcomputer or interpreted
microcontroller such as the netduino or Basic Stamp. Our
wonderfully-written Neopixel library for Arduino supports these
pixels!  As it requires hand-tuned assembly it is only for AVR
cores but others may have ported this chip driver code so please
google around. An 8MHz or faster processor is required.
Comes with one quarter ring of 15 x individually addressable RGB LEDs
assembled and tested. We recommend you buy four to build the full
circle as this is just the 1/4 of the circle.
* Outer Diameter of Full Circle (four put together): 6.2"
* Inner Diameter of Full Circle (four put together) 5.625"
* Width of individual section: 6mm/0.2"
* Height: 2mm/0.1"
* Weight of individual section: 4.03g
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.
