PRODUCT DESCRIPTION
The WS2812B 4 x 4 RGB LED Module is a circular development board with built-in full-color driving lights and a round black shape. It has 16 super bright smart NeoPixels LED arranged in a 68mm outside diameter circular PCB.
These ring RGB lamps can be easily connected by cascading one’s output pin to another’s input pin (DI-DO).
This way, you can control as many LED lights as you want with only one single chip, because each LED lamp has a driver chip integrated in it that makes it intelligent and addressable.
Each LED has a constant current drive of -18mA, so the LED color will be very consistent, even if the voltage changes. You don’t need an external resistor to limit the current and make the RGB lamp ring design slim, as you can see it is simple and easy to use. You can drive the RGB lamp ring with a 5V power supply.
Single wire communication reduces the pressure on the I/O port, and the use of the RGB WS2812B driver chip simplifies the circuit to only need a single capacitor. This gives you a beautiful experience. Moreover, this RGB ring can be cascaded with other RGB lamps using the same chip through a simple Dout input port, without worrying about the shape limitation.
Note : HW-223 printed on module functionality remains same.
Features:
- The LED and the control circuit have a common power source.
- The control circuit and the RGB chip are integrated into a 5050 component package, which allows for complete pixel control.
- The built-in signal reshaping circuit ensures that the wave-form distortion does not accumulate after passing to the next driver.
- The built-in electric reset circuit and the power lost reset circuit prevent errors due to power fluctuations.
- Each pixel of the three primary colors can achieve 256 brightness levels, resulting in 16M colors for full-color display, and the scan frequency is at least 400Hz/s.
- The cascading port transmits the signal by a single line.
- The transmission signal does not require any additional circuit for distances greater than 5m between any two points.
- The cascade number is at least 1024 points when the refresh rate is 30fps.
- The data transmission speed is 800Kbps.
- The light color is highly consistent.
- The module is a full-color soft light strip.
- The LED can be used for decorative lighting, indoor/outdoor LED video screens with irregular shapes.
