Witop Dc5v Addressable Ws2812b 5050smd Rgb LED Ring Light

June 12, 2017/in Blog /by admin

This NeoPixel ring from Adafruit consists of 16 individually addressable RGB LEDs that can all be controlled with a single digital output of a microcontroller and chained together with other rings and SK6812/WS2812b-based LEDs to make larger, more complex displays. This small ring has a 1.75″ (44.5 mm) outer diameter and 1.25″ (31.8 mm) inner diameter.

We also carry two other types of LED rings: a 24-LED ring with a 2.6″ (66 mm) outer diameter and 16-LED quarter-circles that can be combined to make a 32-LED ring with a 6.2″ (158 mm) outer diameter.

The ring can be controlled by many microcontrollers, but our A-Star 32U4 Micro works particularly well for applications where space is an issue since it fits neatly inside the ring. The picture on the right shows an A-Star 32U4 Micro controlling three different sizes of NeoPixel rings. See the Protocol section near the bottom of this page for some things to consider when selecting an appropriate microcontroller.

The Adafruit NeoPixel library for Arduino makes it easy to use an Arduino-compatible board to control the ring’s LEDs, and since NeoPixels are based on the same SK6812/WS2812B LEDs as our Addressable RGB LED Strips, you can also use our Arduino library for addressable RGB LED strips, Example AVR C code for addressable RGB LED strips, and PololuLedStrip mbed library to control the ring.

Connections

The pin labeled Power Signal Ground is the ground pin, and should be connected to the ground pin of the microcontroller that is controlling the LEDs and also to the negative terminal of the power supply. The version of this product shipped by Pololu after September 10, 2014 include a second ground pin close to the first.

The pin labeled Power 5V DC is the power input pin, and should be connected to a suitable power supply. An input voltage of 5 V is used to power the ring, and each LED on the ring can draw up to 50 mA at 5 V when outputting white at full brightness. That means the ring could draw up to a maximum of around 800 mA.

The pin labeled Data Input is an input that receives the signal controlling the LEDs. This pin should be connected to a microcontroller output pin or to the signal output pin of a SK6812/WS2812b-based LED product.

The pin labeled Data Out is optional. It can be connected to the data input pin of another SK6812/WS2812b-based LED product in order to form a chain.

Our 0.1″ header pins could be used to connect to the ring’s four pins, or wires could be soldered directly to the board. The ring does not ship with any header pins or connectors.

NeoPixels can be easily damaged if proper precautions are not taken when using them. In general, for SK6812/WS2812B-based products, we suggest adding a capacitor of at least 10 μF between the ground and power lines and a 100 Ω to 1000 Ω resistor between your microcontroller and the signal input pin. More details on best practices when using NeoPixel products can be found in the Adafruit NeoPixel Uberguide.

Protocol
The NeoPixels are controlled by a simple, high-speed one-wire protocol that requires sub-microsecond timing. The details of this protocol are explained in the Adafruit NeoPixel Uberguide. It is generally not possible to generate the required control signals directly from older, slower microcontroller boards, like the Basic Stamp, or from processors that run full operating systems and can experience multithreading delays, like the Raspberry Pi.

WS2813 VS WS2812B LED Strip
The image is mainly about the difference between the work principle of WS2812 and WS2813 LED strip. The most obvious difference is: when the led one of the WS2812 was broken, it will affect the other led working, but the WS2813 will not appear above situation.

If you don’t know the WS2812 or WS2813, please allow me to introduce them to you.

Generally speaking, WS2812 has two versions: WS2812 and WS2812B. WS2812B is an upgraded version of WS2812. They are an integrating control circuit and the intelligent external control LED source of the light-emitting circuit, which looks similar to the 5050LED. It internal included intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant current control part, effectively ensuring the pixel point light color height consistent. They can be applied to the full-color module, full color soft lights a lamp strip, led decorative lighting and the indoor/outdoor led video irregular screen. The features and benefits between WS2812 and WS2812B is the WS2812B has intelligent reverse connect protection and the power supply reverse connection does not damage the IC.

Nowadays it comes to the latest version of the WS2812, which is WS2813
Compare with the former, WS2813 both have some places similar to WS2812, and have its own unique features：

Common:

1) The control circuit and the LED share the only power source.

2) Built-in electric reset circuit and brown-out reset circuit.

3) The color of the light was highly consistent, cost-efficient.

4) WS2813 LED can use same controller as WS2812B LED.

5) When the refresh rate is 30fps, cascade numbers are not less than1024 points.

6) Send data at speeds of 800Kbps and so on.

Difference:

1) WS2812 only one data signal when one led broken may affect the other led working, which only die is package in 5050 RGB LED Chip. But WS2813 led have 2 data signal, any pixel’s failure won’t affect signal transfer and its total emitting effect, unless two consecutive adjacent LED are Broken. WS2813 adopted the upgraded chips led so WS2813 led make digital led project is more reliable than before.

1, Product Overview :

SK6812 SIDE is a smart LED control circuit and light emitting circuit in one controlled LED source, which has the shape of a 4020 LED chip. Each lighting element is a pixel, and the intensities of the pixels are contained within the intelligent digital interface input. The output is driven by patented PWM technology, which effectively guarantees high consistency of the color of the pixels. The control circuit consists of a signal shaping amplification circuit, a built-in constant current circuit, and a high precision RC oscillator.

The data protocol being used is unipolar NRZ communication mode. The 24-bit data is transmitted from the controller to DIN of the first element, and if it is accepted it is extracted pixel to pixel. After an internal data latch, the remaining data is passed through the internal amplification circuit and sent out on the DO port to the remaining pixels. The pixel is reset after the end of DIN. Using automatic shaping forwarding technology makes the number of cascaded pixels without signal transmission only limited by signal transmission speed.

The LED has a low driving voltage (which allows for environmental protection and energy saving), high brightness, scattering angle, good consistency, low power, and long life. The control circuit is integrated in the LED above.
