I have a WS2811 pixels installed on my house. I have a standalone peak that is tough to get to so I have a long string of pixels then I ran wire from the end of that string back to the peak ~30ft of wire. What I find is that the first pixel after that long run burns out every year. Wondering why and…

For consideration - could you not reverse the data direction of the upper eave and run a line to the near end? then just list that string as a segment with reverse direction? [shorter] Next - I’d be curious how the pixel is ‘burning out’ - does it seem to be the actual LEDs? (maybe the nodes af…

Mostly good ideas. One note - the TxRx pairs have termination resistors builtin to specifically handle the reflected/mismatched signals. That’s part of why differential signals work so well for longer distances, they try and match the impedance of their transmission lines. They also have circuitry…

Quindor offers a dif’ Rx/Tx pair that says it does 5v/12v and is likely of good quality: Info: Diff-Solo - quinled.info QuinLED Diff-Solo specifications - quinled.info QuinLED Diff-Solo Buying Page - quinled.info

It looks dumb the way I have it but thats because I initially wired it up like the blue. I had issues with LEDs burning out which sucked because then I lost the rest of the strip on the lower level. I changed it to be the red that way, if I have a burnout I just lose the peak and everything else loo…

Wow. Definitely sorry to hear of all the burn-outs! What nodes are these? To do the green, you’d have to physically reverse the data flow direction of the nodes, then program them as a reversed segment of nodes. But it seems like your blue scheme sort of did that - and you say, still burned out …

There is no easy way to get the Data In point at the opposite end without physically reversing the strip (or run along Data In, TxRx, etc.). If you do end up moving the Data Input side, you could also consider driving the 2nd Strip from a separate GPIO on the ESP32. It will still look like one lon…

What am I doing wrong here. I have 2 pixels to test on either side. Here is what I am finding. The first 2 pixels are working. The TX light is on solid. No lights are on, on the RX board. The 2nd 2 pixels are on just solid white. [image]

Whats even more confusing to me is when I disconnect the 5VDC converter then all the pixels work correctly but not LEDS are on the the TxRx boards. [image]

I’m not familiar with those boards at all, so just a wild a$$ guess here. But if I had to do it, the nodes on the left, I’d tie that data line to the Rx on the left board, then come out of the Tx on the left board and into Rx on the right board, then out of Tx on the right board into the nodes. It…

Here is a thread with a similar question answered by Divsys and a few others ESP32 long data wire, any issues with this wiring?
