NeoPixel FeatherWing
Quite possibly
The Cutest Thing in the History of Cute
Little Things,
the NeoPixel
FeatherWing (http://adafru.it/2945) is is 4x8 pixel matrix
that fits
perfectly
atop any of our Feather microcontroller
boards (https://adafru.it/l7B).
The NeoPixels are normally controlled from digital pin 6,
but pads on the bottom make this reassignable. In
particular, the default pin for Feather Huzzah ESP8266
must be moved, try pin #15!
The NeoPixel Featherwing is RGB only; there’s no
RGBW version.
Pimoroni Unicorn Hat
The Pimoroni Unicorn Hat (http://adafru.it/2288) is aptly
named after a mythical animal — normally we’ll say that
NeoPixels don’t work with the Raspberry Pi, but
Pimoroni has worked up some magical
software (https://adafru.it/lCx) that makes this
combination possible! It’s an 8x8 RGB matrix that fits
neatly atop the Raspberry Pi Model A+, B+ or Pi 2.
Due to the way Unicorn HAT works, you can't use your
Pi's analog audio alongside it. If you see odd random
colour patterns and flickering make sure analog audio is
disabled.
