Using two neopixel-style strips in a single blade - config?

Proffieboards
1

Hi. I’m building my first saber with a proffieboard v3.9, and looking to create a blade by sticking two neopixel-style strips back to back.

I’m not sure how to tell the configurator this, though.

What options do I select for this? Is it WS2811 / neopixel in the first slot, then, say, Neopixel Dual for the other one? Or do I just wire the two reds to the same pin, the two greens to the same pin, etc? Or solder it together in one mahoosive strip and fold it in half?

Thanks for any help!

Normally, when you do this, the two strips operates in parallel, and ProffieOS doesn’t have to know.
If you make the folded strip, we call that a zig-zag blade, which is also supported by using subbladereverse().

Amazing, thanks’

SomI’m going to:

  • cut both strips to the same length
  • connect both Live wires to BATT+
  • connect both data wires to DATA1
  • connect both earths to GRD
  • choose WS2811/neopixel in tbe configuration tool

Thanks again!

Normally you would connect this to LED2+3.
That way the proffieboard can cut the power to the LED strips, which saves power when they are off anyways. (LED strips tend to draw ~1mA per LED even when off.)

oh cool, thanks! that saved me from a mistake!
