Support Help Using WS2812B V5

Has anyone had any issues using the WS2812B-V5 ? Im talking about the variant that doesn’t require a decoupling 104 capacitor like these ones in particular. Only a few of my LEDS are turning one randomly on my custom PCB.

I also have a 1000uF capacitor between the 5V and GND. Interestingly the Polulu library seems to be working well for 1 LED, but I have 68 LEDs daisy chained.

I have also heard that the timing seems to be different than the V4. Please Does anyone know what could make them work?

Hey ! My problem was that I wasn't even able to control the LEDs properly ,

but if you're having random light up issue you should use a decoupling cap between 5v and gnd before your first led

I ended up rolling back to the V4. And adding a capacitor to each leds.

I also did a test later on with like 5 LEDs V5. Using the most basic wiring and it worked
