Hi,
extremely new user here, both for electronics in general and of KiCad (v6.07 on Windows).
I have designed a schematic with a chain of WS2812B LEDs. For only the first of them the ERC flags the power pins as not connected. The other LEDs are fine. I have tried reconnecting them but that does not help.
I can not see a difference when using the “highlight wires and pins of a net” tool. I can select any of the wires and pins on the component that shows the error and on the ones that don’t. The highlighted net and pins on other components look good to my (very) untrained eye.
Also all seems correct in the PCB layout. I had rats nest connections displayed for both offending pins and had to route them. The DRC comes up without any problems.
A screenshot illustrating the problem can be viewed at https://imgur.com/a/Q38J8jQ
The KiCad project is available at GitHub - MarianAldenhoevel/DoorSign: A PCB-Design to be used as door-sign if you want to take a look.
Thank you for reading!
