Currently, there is no stock, but we will receive it soon. You can buy it and we will ship the order as soon as it comes back available (normally from 1 to 3 weeks).
Orders that include an On Demand or Back Order item will be shipped when they are available again in one shipment. This means the order will take from 1 to 3 weeks to be shipped once the order is placed You will be notified when adding a backorder product in the cart. If you want to receive first the items in-stock, please, place two different orders separating the in-stock and On Demand or Back Order items.
This product is only available for search (tutorials, schematics...). They can not be purchased.

NeoPixel Ring - 24 x WS2812 5050 RGB LED with Integrated Drivers
* Required fields
Round and round and round they go! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6" (66mm) outer diameter. 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 as a single ring with 24 individually addressable RGB LEDs assembled and tested.
