Led Stick PCB

Tomsauy , 01-13-2025, 10:00 AM

Hi all,
I am try to create my own LED stick with Easy EDA Pro.
I use SK6812 Mini LED, and I read on technical spec that it is better to put 0.1F capacitor short to the LED.
But I am not sure how to place it on PCB.
I have put 3 screens of 3 different ideas I have, but not sure sure which is the better or if there is wrong design.
I am clearly a beginner, no electronical formation (except many videos of @Robert Feranec thanks to him for his amazing job 🙂 )
Thanks in advanced for your help 🙂

direct track connection on the same layer between the pins is the best connection

Thanks for your answer 🙂
I watched this video, but I think it's beyond my skill level 😦 , and I had a hard time understanding it.
So, if I understand correctly, it is better to route like in the picture instead of using inner layer for 5V and route with VIA ? (I keep VIA and inner layer for GND only)

you can route power in inner layers. just the connection between cap and led pin is the best to have on the same layer

for this kind of circuit I don't think it is critical. but because you have the components on the same side of the pcb then it is good to connect decoupling capacitor pin with the led power pin with a direct track between them. power itself can be routed on other layers.

OK so like this ?
Thanks again for your help ! 🙂
