This RGB LED strip makes it possible to control each LED individually on a self-adhesive strip of only 10mm wide. To get the strip that thin is possible due to the WS2812B controller chip is in the LED itself. This is kinda cool, but because the WS2812 chip uses a special protocol with only one wire, timing is very important. This means the strip is perfectly controllable using an Arduino Uno/Mega 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, NETduino, any other interpreted/virtual machine microprocessor or any processor slower than 8 MHz.
Sold per meter. If you order 5 meters, you get a complete reel with connectors on both ends. If you order any other length you may have one or even no connector included.
