Parameter Input voltage: DC5V Led SMD Qty: 60pcs RGB SMD5050 per meter Length:16.4ft /5m Power:18W/m, total is 90W Signal: WS2811 chip built-in 5050SMD Wave length(NM):R,650nm ; G,520nm ; B,460nm View angle:120 Dimension:L196* W0.47 * H0.12inches PCB color: Black Life span:?50000hrs Warranty:2year Waterproof: IP67 waterproof Package: 1x 16.4ft WS2812B LED strip light Kindly note : 1) It comes without power supply. 2) These LED's use about 9.5 Watts max (~2 Amps @ 5V) per meter. 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 5V 10A supply is key! 3) 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 timing-specific and can only be controlled by microcontrollers with highly repeatable 100nS timing precision. Uno/Mega microcontroller at 8MHz and 16MHz, and with a little effort you can use Beagle Bone Black , but it will not work with the Basic Stamp, NETduino, any other interpreted/virtual machine microprocessor or any processor slower than 8 MHz. 4) the entire strip must be buffered in memory, UNO projects only have about a 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.
