They are not fully compatible but almnost every task you can somehow achieve with both. I gues you can use UNO R3 instead of provided Zero in your project as well. But Zero is more modern and has faster CPU, so give a try. Biggest difference is likely that UNO R3 use 5V logic while newer Zero is 3.3V.

While current content terms and conditions does not say anything about it, in history it was mandatory to use at least two parts from kit, but usage of whole kit was not mandatory.

Is there any specific document for circuit design using this LEDs from Wurth? Like things to consider and best practices etc?

Look at their webpage. There are datasheet, brief explanations, link to application note and most notably, recording of webinar, which explains lot of things including some best practices.

misaz  If this 14.5 you are referring referring to Max I(F,IC) of  1315050930002, then it is the IC Output current to each individual IC. Take a look at ANO009 (https://www.we-online.com/components/media/o782907v410%20ANO009b_Understanding%20parameters%20in%20ICLED%20datasheets_EN.pdf) at page 4, it says the Value you are probably referring to is per LED and therefore when all thee lights are turned on at fuull brightness, it will be 14.5x3mA obones do check out the document

Hi,
So, I looked at basic schematic from the above and found that there was no capacitor on one of the schematics using LEDs.? 

And also, I saw some documents and one webinar on the link you have posted, there was not much on PCB or circuit design best practices.

decoupling caps? you should definitely put it. 100nf near each LED and may me 10uF around start of each strip. if the LED color isnt gonna drastically change (gently fade from zero) you can get away without individual caps for each LED.

I do not know what schematics you refer to. Even simplified schematics on directly linked page shows capacitors.

I did not watch full webinar, but If there are not any concrete PCB layout requirements, follow standard one (ground plane under LEDs, wide VCC trace because high currents flow through it, etc).

Ok. look on the first schematic. BTW this is not serious because, I always follow the standard rules as much as I can. So, I know the above rules. Nevertheless, if there is any specific parameter in that case such guides can help us. That's why.

Thanks man..!

Ahh, now I understand what schematics you mean. On this schematics, following caps serves the purpose:

It works because featherwing is pretty small board and LEDs are still near the caps. But if you do something longer, I would recommend staying at old good 100nF near each chip (LED).
