NeoPixel Strips and

Strands

The most popular type of NeoPixels are these flexible LED strips…they can be cut to length and fit into all manner of

things. We’ve got over a

dozen varieties! Two vital things to be aware of:

Though strips are described as “flexible,” they do not tolerate continuous and repeated bending. “Formable”

might be a better word. A typical application is architecture, where they can be curved around columns and then

stay put. Repeated flexing (as on costumes) will soon crack the solder connections. For wearable use, either affix

shorter segments to a semi-rigid base (e.g. a hat, BMX armor, etc.), or use the individual

sewable NeoPixels

shown later.

Watch your power draw. Though each pixel only needs a little current, itadds up fast…NeoPixel strips are so

simple to use, one can quickly get carried away! We’ll explain more on the “Powering NeoPixels” page.

RGB NeoPixel Strips

NeoPixel Digital RGB LED Weatherproof Strip is

available in three different “densities”: 30, 60 and 144

LEDs per meter, on a white or black backing strip.

30 LEDs per meter, white

30 LEDs per meter, black

strip (http://adafru.it/1460)

60 LEDs per meter, white

strip (http://adafru.it/1138)

60 LEDs per meter, black

strip (http://adafru.it/1461)

144 LEDs per meter, white

strip (http://adafru.it/1507)

144 LEDs per meter, black

strip (http://adafru.it/1506)

The

approximate peak power use (all LEDs on at

maximum brightness) per meter is:

30 LEDs: 9 Watts (about 1.8 Amps at 5 Volts).

60 LEDs: 18 Watts (about 3.6 Amps at 5 Volts).

144 LEDs : 43 watts (8.6 Amps at 5 Volts).

Mixed colors and lower brightness settings will use

proportionally less power.
