Datasheet
These are similar to the sewable Flora NeoPixels, but
with a pin arrangement that (with the addition of
headers) fits neatly into a breadboard for prototyping.
Also available in two formats:
Pack of 4 (http://adafru.it/1312), ready to use as-is.
Sheet of 25 (http://adafru.it/1558), cut off as
needed.
For both types, headers (http://adafru.it/392) are
optional and not included.
Breadboard-Friendly NeoPixels measure 10.2 x 12.7
millimeters (0.4 x 0.5 inches) and are RGB only; there’s
no RGBW version.
