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 a 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 re-modeling 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.

Features:

1. Intelligent reverse connects protection, the power supply reverse connection does not damage the IC.
2. The control circuit and the LED share the only power source.
3. Control circuit and RGB chip are integrated into a package of 5050 components, form a complete control of pixel point.
4. Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.
5. Built-in electric reset circuit and power lost reset circuit.
6. Each pixel of the three primary colors can achieve 256 brightness levels, or 16M colors full-color display, and scan frequency not less than 400Hz/s.
7. Cascading port transmission signal by a single line.
8. Any two points the distance more than 5m transmission signal without any increase circuit.
9. When the refresh rate is 30fps, cascade number is not less than 1024 points.
10. Send data at speeds of 800Kbps.
11. The color of the light was highly consistent
12. Full-color module, Full-color soft lights a lamp strip.
13. LED decorative lighting, Indoor/outdoor LED video irregular screen.
