All your high-density LED dreams answered, yet there are a few things to watch for.

First up, the ultra-high density means much higher power usage over a certain distance -35 Watts max (~7 Amps @ 5V). The max rating is assuming all the LEDs are on full white, usually the actual current for colorful design is about 1/3 to 1/2 the max current. A good power supply such as our 5V 10A supply is key!
Second, to get high density, the controller chip is inside the LED, which is kind of cool, but also means that the chip only uses a single pin for input and a single pin for output. The protocol used is very very timing-specific and can only be controlled by microcontrollers with highly repeatable 100nS timing precision. We have example code for using with the Arduino Uno/Mega microcontroller at 8MHz and 16MHz, but it will not work with the Raspberry Pi, Basic Stamp, NETduino, any other interpreted/virtual machine microprocessor or any processor slower than 8 MHz. For those processors, check our 32 LED/meter digital LED strip which has SPI-like input/output and works well with Pi, NETduino, and other processors.
Third, just because you have all those pixels doesn't mean you have the RAM for it - the entire strip must be buffered in memory, and we've found many Arduino UNO projects only have about 1500 bytes of RAM available after all the extras are included - enough for about 2-3 meters of the 144 LED pixels. If you want to drive multiple meters and have some other libraries included, use a Mega.
This strip now comes with a weatherproof sheathing, you can remove it if not wanted, with a pair of scissors

LED strip 一條

144 LEDs per meter
Maximum 5V @ 60mA draw per LED (all LEDs on full brightness)
5VDC power requirement (do not exceed 6VDC) - no polarity protection!
1 integrated RGB LEDs per segment, individually controllable
LED wavelengths: 630nm/530nm/475nm
Connector: 3-pin JST SM
Dimensions: 1000mm x 12mm
Power Lead: 196.85mm
Connect Lead: 92.07mm

We currently ship this product with the WS2812B 4-pin chip LED installed. Previous versions may have come with the WS2812S 6-pin LED. Both B and S LEDs can be chained together and are compatible with the NeoPixel Libary. The 'B chip type adds additional polarity protection and is the same brightness as the 'S type.
