That won’t do. Now what?

Because NeoPixels use a fixed-frequency clock, options are limited. You can’t switch out for a faster microcontroller

and expect substantially different results.

One option is to use a different LED type, such as our DotStar or LPD8806 strips, or WS2801 pixels. These can be

driven at higher data rates, though they do have some other tradeoffs with respect to NeoPixels (cost, color

resolution and/or pixel density).

Another is to develop your own code on a more capable microcontroller or an FPGA that drives

multiple NeoPixel

strips

in parallel. One such project — OctoWS2811 for the Teensy 3 microcontroller — is shown later. This sort of thing

is a complex undertaking and not recommended for beginners. And even among more experienced programmers,

there’s often an unreasonable over-emphasis on data rates when the

real bottlenecks lie elsewhere…don’t dwell on

this too much unless you can confirm it’s the root of the problem.
