These are great little WS2812B RGB Addressable LED Module. They are very small, not even a centimeter in diameter. You can daisy chain multiples of these modules together and control each LED individually (addressable LEDs).
WS2812B is an intelligent LED light source control that the Circuit and RGB chip control are integrated into a 5050 Components package. Its internal data includes intelligent digital door locks and signals remodel loop amplification drive. It also includes an internal precision oscillator and a 12 V constant voltage programmable current control part, effectively ensuring the bright pixels color consistent height point.
The data transfer protocol uses single NZR communication mode. After the pixel power-on reset, the DIN port receives data from the controller, the first pixel collects 24bit initial data then sent to the internal data locks, the other data that remodeling by the internal signal reshaping amplification circuit sent to the next cascade Pixel through of the Do Port. After transmission to each pixel, the signal to reduce 24bit. Pixel adopts Auto reshaping transmission technology, causing the cascading pixel number is not limited to the signal transmission, only depends on the speed of the signal transmission.
LED to low voltage conduction, environmental protection and energy saving, high brightness, scattering angle is great, Good consistency, low power consumption, long life and other advantages. The integrated control chip in the LED circuit above becoming simpler, small volume, convenient installation.
