WS2812B RGB SMD LED (Strip of 10)

The WS2812B may look like a common 5050-sized (5x5mm) SMD LED, but there’s actually an integrated control circuit embedded inside there too. If you look really hard, you can see the tiny black chip hidden in there, along with minuscule gold wires connecting the chip to the LED. This LED is certainly more than meets the eye! The ‘B’ at the end of the WS2812 name denotes that these specific LEDs are equipped with and only require FOUR pins instead of SIX!
The LED itself is unlike most RGB (Red/Green/Blue) LEDs. The brightness of each color can be adjusted using a serial string to one of 256 different levels. That means there are 16,777,216 (2563) possible combinations of colors. You can produce any color from white to black (off), or salmon to sienna.

WS2812B Features:

  • Intelligent reverse connect protection, the power supply reverse connection does not damage the IC
  • The control circuit and the LED share the only power source
  • The control circuit and RGB chip are integrated into a package of 5050 components, form a complete control of pixel point
  • Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate
  • Built-in electric reset circuit and power lost reset circuit
  • Each pixel of the three primary colours can achieve 256 brightness display, completed 16,777,216 colour display, and scan frequency not less than 400Hz/s
  • Cascading port transmission signal by a single line
  • Any two points the distance more than 5m transmission signal without any increase circuit
  • When the refresh rate is 30fps, the cascade number is not less than 1024 points
  • Send data at speeds of 800Kbps
  • 4-pin Design
