Hi, new here and as usual leaving everything till the last minute :D
Anyway i'm building a small megatree, 18 strips of WS2812bs, each strip will be 1.5M long with 90 pixels, I have all my wiring sorted and mounting frame etc but before I begin I have a couple of questions.
Going to be running it using an ESP32 with WLED installed, can I have one single string of pixels which would be 1620 (power injection is sorted) or should I be breaking it up into 2, 3 or 4 seperate strings, obviously I can enable more outputs in the hardware setup on the ESP but need to make sure I get the hardware setup and build right before moving on to xlights integration.
Thanks
Dave

I'd say the more outputs the better. How many pixels do you want to die if one goes bad? Also there is a mathematical limit to the number of pixels that can be sent data during a time slice depending on the frame rate you are running. I seem to remember somewhere around 600-700 pixels a Falcon board would have to drop from 25ms to 20ms updates and I can't believe an ESP32 could outperform an FPGA device.

Thanks for the info
