Specs:
- LED: NeoPixel with 1515 RGB LED
- Operating Voltage: 5VDC
- IP20 (not weather proof at all)
- Luminescence: R: 18lm / G: 58lm / B: 8lm
- Beam Angle: 120º
- These LED's use up to 10 Watts max (~2 Amps @ 5V) per meter. The max rating of 4.5A is assuming all the LEDs are on full white, usually the actual current for colorful design is less than 1/3 of the max current. A good power supply such as our 5V 2A or 5V 4A supply is key!
- The strip is very thin and does not transfer a lot of heat, so don't have all the LEDs on bright white all the time or you could get thermal damage.
- 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, and with a little effort you can use with the Raspberry Pi, or Beagle Bone Black, but it will not work with the Basic Stamp or any other interpreted/virtual machine microprocessor or any processor slower than 8 MHz. For those processors, check our DotStar digital LED strip which has SPI-like input/output and works easily with Pi and other processors.
- The way the pixels are controlled by an Arduino, the entire strip must be buffered in memory, and we've found many Arduino UNO projects only have about 1500bytes of RAM available after all the extras are included - enough for about 500 LED pixels. If you want to drive the entire strip and have some other libraries included, you may need to use a Mega.
