144 LEDs : 43 watts (8.6 Amps at 5 Volts).60 LEDs: 18 Watts (about 3.6 Amps at 5 Volts).30 LEDs: 9 Watts (about 1.8 Amps at 5 Volts).The approximate peak power use (all LEDs on at maximum brightness) per meter is: NeoPixel Digital RGB LED Weatherproof Strip is available in three different “densities”: 30, 60 and 144 LEDs per meter, on a white or black backing strip. Though each pixel only needs a little current, it adds up fast…NeoPixel strips are so simple to use, one can quickly get carried away! We’ll explain more on the “Powering NeoPixels” page. a hat, BMX armor, etc.), or use the individual sewable NeoPixels shown later. For wearable use, either affix shorter segments to a semi-rigid base (e.g.

Repeated flexing (as on costumes) will soon crack the solder connections. A typical application is architecture, where they can be curved around columns and then stay put. Though strips are described as “flexible,” they do not tolerate continuous and repeated bending.We’ve got over a dozen varieties! Two vital things to be aware of: The most popular type of NeoPixels are these flexible LED strips…they can be cut to length and fit into all manner of things. Pick a category from the left column for product links and tips & tricks specific to each type of NeoPixel. NeoPixel products are available in a zillion form factors…from individual tiny pixels to huge matrices…plus strips, rings and everything in-between. Time: NeoPixels process data from the host microcontroller at a fixed data rate more pixels = more time and lower animation frame rates.Power supplies likewise have some upper limit. Power: each NeoPixel draws a little bit of current more pixels = more power.It’s only a few bytes each, but as most microcontrollers are pretty resource-constrained, this becomes a very real consideration for large projects. RAM: NeoPixels require some RAM from the host microcontroller more pixels = more RAM.There’s no inherent limit in the maximum length of a NeoPixel chain, but eventually you’ll encounter any of various practical limits: Is there a limit to the number of NeoPixels in a chain? For POV use, DotStar strips will look much better (they have about a 20 KHz refresh rate).ĭefinitely! The slower movement used for photographic light painting doesn’t call attention to the limited refresh rate the results look great, especially with a light diffuser. The refresh rate is relatively low (about 400 Hz), and color displays in fast motion may appear “speckled.” They look fine in stationary displays though (signs, decorations, jewelry, etc.). This is why we continue to offer other LED types some are more adaptable to certain situations.Ĭan I use NeoPixels for POV (persistence of vision) displays? The control signal has very strict timing requirements, and some development boards (such as Netduino or Raspberry Pi) can’t reliably achieve this. NeoPixels aren’t the answer for every project.If this is a new experience, work through some of the beginning Arduino tutorials to get a feel for the language. To create your own effects and animation, you’ll need some programming practice.

Red, green and blue LEDs are integrated alongside a driver chip into a tiny surface-mount package controlled through a single wire. The WS2812 Integrated Light Source - or NeoPixel in Adafruit parlance - is the latest advance in the quest for a simple, scalable and affordable full-color LED.
