Spliting data on RGB strip

Other Hardware General Electronics

Hi all

Fairly sure this will be OK, but thought it worth checking first... not in the mood for the puff of smoke moment tonight.

I have several strips of WS2812b controlled RGB leds. All fine there.

One of the strips has a few obstacles in the way, so I planned to simply cut out the sections where required, and link the data off the adjacent strip at the required aligned data point.

Any reason that won't work?

I don't have enough programming space to allocate a data stream to each individual strip.

Terrible image attached to help explain

Not sure what the fanout is for a pixel.

Looks like it would work.

You could experiment with some short strips.

I would use a separate resistor for each strip not a common one.

And run a ground wire alongside every data wire.

I would pull GND and power from the spot where also the data is coming from (observing the maximum current-draw for the strip, eg the total length of the strips added) The logic output of the WS2812-chip is relative to it's Power/GND.
