hey there, so I posted a while back because I had a problem interfacing WS2812B leds with a Wemos D1 mini because the first led kept flickering no matter what I did. My quick and dirty approach was to just put the led in front of the strip in a casing, add this extra led in the software and I was done. Now I decided to upgrade and bought a 74HCT245D module and ordered my own PCB. This is the schematic:
And this the pcb:
I also have a video of the situation: https://photos.app.goo.gl/qUyAzfQJnhKixZxu7
I checked every connection, everything seems fine and should be working.
I also added a DS3231 module which I forgot to add on the pcb but this shouldn't interfere with any of the leds, right?
Does anybody got an idea what could be the cause?
Also don't be harsh on my schematic and pcb, this is the first time I designed something like this
