How can replacing of LED WS2811 with WS2815B on the strip???

Greetings all

I have a RGB-bord with a WS2811 5050 LED, and this LEDs are not addressable.
In the attached image, I want to replace this LED with WS 2815!!!
How to replace these LEDs with WS 2815?
Is this possible? Can I address these LEDs without changing them?

Thank you all

With so little information to base any advice on, I would say not possible because ws2811 may be 12V but ws2815 is 5V. Also because ws2811 are addressable, so if your board does not allow you to address them, changing the led will not help.

Thanks mate.

But, i have this little guys:

and they are 12Volt:

OP's link but clickable:

They will not work on your board. With ws2811 the chip is separate from the led. The data signal does not go to the led, only to the chip. PWM signals go from the chip to the led. With ws2815, the chip is inside the led and data goes to the led.

The part on your board now looks like a 'dumb' RGB LEDs. 3 colors, controlled from other electronics.

The link to the WS2815, you can see the control chip that is internal to the LED. It is controlled with Neopixel library or fastLED.h library, using special high speed timing.

What is the rest of your board? Do you have a schematic?

Thanks for reply.

I made a circular bord for RGBs. This is so lock lick to below strip:

This bord not included RGB controller.

Ok, those are not addressable RGB LEDs, they are just 3 LEDs in a package, with external electronics to control the cathode of each LED. Basically 3 N-channel MOSFETs to connect the LED cathode to Gnd while a common anode provids power to the package.

Addressable LED needs power, Gnd, and data line that goes into the chip, the chip passes the data to the next chip.

See this picture - in both cases, the three RGB LEDs are in a 5050 SMD package - but the addressable LEDs also have chip that accepts the serial stream of data, 3 bytes/package, tell it what PWM level to use per LED. All LEDs can be different brightnesses.

The dumb strip, the whole strip shows the same color, with brightness controlled by whatever PWM might be controlling the MOSFTs.

Thank you soooooo much for reply.
What can i do?

Pull LEDs & resistors off the board, cut traces, rewire it?
I wouldn't want to hack up that many signals.
Be easier to get some perfboard and wire up thru hole parts

Or redesign and order new boards. $9.90 for ten up-to-5cm x 5cm boards from iteadstudio.com,
$19 for ten up-to-10cm x 10cm boards.

Why does that diagram say "resistors not shown" on the addressable LEDs?

In case they were used with WS2815, I hadn't looked at the datasheet

But the WS2815 - like the WS2811 and WS2812 and others in the category - has constant-current drivers, not resistors!
