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.

This LED strip has a water-resistant layer such that it can be used in humid areas, for example. Please note, if you shorten the strip, it is no longer water-resistant at the end. In addition, the layer has an insulating effect, which prevents proper heat dissipation. We therefore advise against letting the LED be lit continuously at maximum power, as the lifespan will then deteriorate more quickly. There is double-sided tape at the bottom of the strip, which makes it easy to stick the strip on something, we recommend doing this on a metal surface so that the strip can lose at least some of its heat.

This LED strip also has a backup data line. If one LED fails, this backup line ensures that the remaining LEDs continue to work. Only if you have two defective LEDs in a row, the rest of the LEDs will stop working, but that chance is small.

See the FAQ at the bottom of this page for instructions on how to connect the strip and what is required.

Product FAQ

What do I need to make a LED strip, ring or matrix work and how do I connect it?

Supplies:

The following components are required to operate a product with digital LEDs:

Stable (CE-approved*) power supply that supplies the same supply voltage as indicated in the product specifications above and that can also deliver at least the maximum current that the strip draws (also found in the product specifications). If you use several strips in a row, multiply the number of LEDs by the current that a single LED draws to calculate the minimum supply current.
Development board for the control (Arduino, ESP32, Raspberry Pi, or similar).
Resistor (470Ω) to stabilize the data line (two if the LED chip also has a clock-pin).
Electrolytic capacitor (e.g. 1000μF 25V) as a buffer for peak currents.
Wires or cables to connect everything. Make sure that the power cables can handle the current that the strip/matrix draws.

The following parts are optional:

Breadboard or experimental circuit board to attach components
Level converter (if the development board has a signal voltage of 3.3V)

Connecting the strip:

Turn off the power before continuing.
Connect the wires (wire color is indicated on the package):
1. First, connect the GND (ground/min) of the LED strip to GND of the power supply (also disconnect this last when disconnecting the strip).
2. Connect the data (DI) wire through a 470Ω resistor to the signal pin of the development board (a level converter may be needed for 3.3V development boards).
3. If the strip/matrix has a backup data line (WS2813/WS2815/etc.): Connect the backup data line (BI) to GND, or to the backup data out (BO) wire of another strip/matrix.
4. If the strip/matrix has a clock pin (APA102/NS107S/etc.): Connect the clock pin via a 470Ω resistor to a signal pin of the development board (a level converter may be required for 3.3V development boards).
5. Connect the power supply wire to the positive of the power supply.
Connect the GND of the strip and power supply to the GND of the development board.
In case of several strips/matrices in a row: Connect an extra external power cable between each meter of LED strip.
Place the large capacitor (1000μF 25V) between GND and the power wire, near the beginning of the strip/matrix.
The power supply can now be switched on. Please note that the LEDs only light up when the development board gives a correct control signal.

*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.

We recommend reading the following pages for more information (especially when using multiple LED strips): Powering Neopixels and Adafruit NeoPixel Überguide.

Why do some LEDs show the wrong color?

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

Voltage drop in supply voltage
Particularly with many LEDs in succession, it can happen that a part does not display the right color. This may be a sign that the supply voltage has dropped too far due to losses in the cabling. This can be solved by using extra thick power cables and connecting them between each strip.
