This is a clone version of the adafruit Neopixel shield. There are 40 WS2812B LEDs in matrix form of 8 x 5 LEDs. These can all be individually controlled via pin 6.
The shield is suitable for all Arduino's that can control these digital WS2812B LEDs via pin 6. and compatible with the standard Arduino shield format and pin layout.

With this (unsoldered) shield a series of male pin headers are included that can be soldered onto the shield. A small green terminal block is also supplied for possible external power supply of the LEDs.
This can be soldered at the location indicated with "Ext.5V". If the external power supply is used, the connection must also be disconnected to the right of this connection (along the small black component that has 3 feet)
The external power supply for the LEDs must be between 4 and 6V DC (5V recommended)

This shield has a Din and Dout like all other WS2812B LEDs. You can find these in the corners of the shield. These can be used to link multiple shields or other WS2812B products to this shield.

Note: This shield can use quite a bit of current when all LEDs are fully on. (white at full brightness) The Arduino you use may not be strong enough and external power is required. This problem can be solved by making the LEDs less bright in the software.

For more information on the control and operation of the WS2812B LED you can read the product description of one of our other products:

Product FAQ

Use a stable, CE-approved power supply with the correct voltage that can supply sufficient current. The maximum current that an LED can draw is indicated on the product page. Multiply this number by the number of LEDs to calculate the total maximum current. This maximum current is the minimum current that the power supply must be able to supply.

The following parts are required to use a product with digital LEDs:

  • Power supply
  • Development board for controlling the LEDs
  • Resistor (470Ω) to limit the current of the data line
  • Electrolytic capacitor (1000μF 25V) as buffer for peak currents
  • Wires or cables to connect everything

The following parts are optional:

  • Breadboard or experiment PCB to connect the components
  • Level converter (in case the development board has a signal voltage of 3.3V)

This can have several causes. The most common causes are:

Signal voltage too low
For example, WS2812B LEDs have a signal voltage of 5V. When these are controlled with a voltage of 3.3V (as with ESP32/ESP8266/Raspberry Pi), data may not be properly received at one or more LEDs, resulting in the wrong color. This can be solved by increasing the signal voltage to 5V using a level converter.

Noise on the data pin
The data pin is sensitive to noise. This can be solved by connecting a 470Ω resistor in series between the microcontroller and the data pin of the LEDs.
