Overview
NeoPixel LEDs are the bee's knees, but in a few scenarios they come up short…
connecting odd microcontrollers that can’t match their strict timing, or fast-moving
persistence-of-vision displays. Adafruit DotStar strips deliver high speed PWM and an
easy-to-drive two-wire interface, bridging the gaps in the spectrum of awesome.
DotStars vs NeoPixels
The basic idea behind DotStars and NeoPixels is the same: a continuous string of
individually-addressable RGB LEDs, driven by a microcontroller. The way each goes about
it is a little different. DotStars aren’t necessarily a better thing in every situation…there are
tradeoffs, each has its pros and cons to consider…
DotStars NeoPixels
+ Extremely fast data

rates, suitable for persistence-
of-vision displays.
+ Easier to interface to a broader range
of devices; no strict signal timing
requirements.
+ More affordable.
+ Wide range of form-factors (pixels, rings,
matrices, etc.).
+ Works from a single microcontroller pin.
– Strict 800 KHz data rate; not all systems can
