WorldSemi WS2812B Digital 5050 RGB LED Strip - 60 LEDs 1m

A digital LED strip of which the color and brightness of each LED can be controlled separately. A lot of LEDs can be placed in sequence and all can be controlled with 1 pin of a microcontroller. Various platforms provide support for this LED by means of libraries, including Arduino and Raspberry Pi.

The strip can be cut between each LED. This makes the strip easy to be shortened or extended. The strip can be easily sticked on something by means of the double-sided tape at the bottom of the strip.

For more information about the LED chip, see the datasheet under the tab "Downloads".

Wire coloring:

• Red: Power supply wire
• Green: Data signal wire (signal from microcontroller or other LED strip)
• White: GND/ground/min wire

Connecting the strip:

1. Use a stable (CE approved*) power supply that can supply sufficient power (minimum is current value above per LED strip).
2. Turn off the power before continuing.
3. Connect the wires:
   1. First, connect the GND (ground/min) of the LED strip to the GND of the power supply (disconnect this last when disconnecting the strip).
   2. Connect the data (DI) wire via a 470Ω with the signal pin of the microcontroller (a level converter may be needed with 3.3V microcontrollers), or the data out (DO) wire from another strip.
   3. Connect the power supply wire to the plus of the power supply.
4. Connect the GND of the strip and power supply to the GND of the microcontroller.
5. In case of several strips in a row: Connect an extra external power cable between each meter of LED strip.
6. Put a large capacitor (1000μF 25V) between GND and the power wire, close to the start of the strip.
7. The power supply can now be turned on.

*There are many power supplies on the market that have a China Export ("fake" CE marking) or carry a CE marking, but are in reality not CE approved. We do not recommend using these, often cheap (Chinese), power supplies because they generally do not provide a stable voltage. A stable voltage is essential to make the LEDS work stable, and to prevent damaging them.
