Adafruit NeoPixel LED Strand 20 LED 4" Pitch
PRODUCT ID: 3631
Description
Attaching NeoPixel strips to your costume can be a struggle as the flexible PCBs can crack when bent
too much. So how to add little dots of color? Use these stranded NeoPixel dots! They're very small, so
they're easy to embed into any structure, costume, or wearable. Each dot is enclosed in a small plastic
weatherproof button, we don't recommend dunking these underwater but they can survive temporary
outdoor usage. Best of all the buttons have little plastic hooks molded into the back so they can be
tack‐sewn in place.
Each strand has 20 dots with a single NeoPixel inside with cabling connecting them. The dots are 4"
apart, we also have a version that is 2" apart.
NeoPixels are 5050‐sized LEDs with an embedded microcontroller inside the LED. You can set the
brightness of each R/G/B/W. Each LED acts like a shift register, reading incoming data on the input pins,
and then shifting the previous data out on the output pin. By sending a long string of data, you can
control an infinite number of LEDs, just tack on more or disconnect unwanted LEDs at the end. The
PWM is built into each LED‐chip so once you set the brightness you can stop talking to the strip and it
will continue to PWM all the LEDs for you.
These NeoPixel strands have 20 digitally‐addressable pixel LEDs per meter. We have a tutorial showing
wiring, power usage calculations, example code for usage, etc. Please check it out!
