HDR Addressable LED strip - SK9822 (APA102 Compatible)

$47.00 USD
$47.00 USD

Why choose these pixels?

These are the most stunning, high-performance LEDs made today. They are brighter and faster than NeoPixels (WS281x) and flicker-free with HDR capabilities.

What is it?

These are flexible RGB LED strips using the SK9822 chipset with HDR capabilities. They are powered by 5V and driven by a clock and data line. These are compatible with APA102s, which are also known/sold as DotStar.

Connectors for input, output, and a 2.1mm x 5.5mm power jack are installed.

Available in pixel densities of 30, 60, or 144 pixels per meter.

These LED strips come either with an adhesive tape back (IP20), or sealed in waterproof flexible silicone tubes to protect against the elements (IP67). They can be easily cut to any length, and have solder tabs between every LED.

What makes these LEDs special?

Pixelblaze is the only commercially available pixel controller that will maximize the per-pixel HDR out of these amazing pixels due to its 32-bit pipeline.

These are state-of-the-art and provide rock-solid updates, faster refresh cycles, and the possibility of a dynamic range well beyond the usual 0-255. They have 24-bit RGB color (8 bits per channel) with an additional 5 bits of brightness control for an equivalent of 13 bits of brightness control. They can be used in very low-light applications without losing color-mixing capabilities, and transitions to black are extremely smooth.

The SK9822 is a clone of the APA102C LED, but improves on the design and can provide the same dynamic range without introducing flicker. They’re also superior to WS281x and APA102s for Persistence-of-Vision (POV) effects due to their speed and some implementation details around PWM and colors.

Notes on this batch

  1. The DC barrel connector has a 2.5mm pin, whereas it formerly had a 2.1mm pin. Some power supply connectors have a 2-sided inner mating conductor that's compatible with either size.
  2. Manufacturers vary greatly on the order of the pins within the JST-SM. Please confirm visually and with a multimeter before connecting power or a Pixelbaze.
