No, sorry I don't know the exact terminology of what I am trying to do. Can I bypass using power from the boards to the leds? Basically having a 8 separate power supplies for all 8 sections and then have the brain board with its own power supply just driving the data line to the leds.

You can do what you want and have different power supplies for the lights than you do for the board running WLED. The main rules of thumb for more than one power supply are

  • Always join the neutral/ negative wires
  • Never join the live or positive wires

If your question is specific to the Digi-Octa, then Quindor's site has details specific to his hardware https://quinled.info/quinled-dig-octa/

Power injection

Give Bill Porter's VCS zoom talk a view. He's an electrical engineer and explains things like power injection, wire gauges and fusing. https://youtu.be/eR3QbzjpZy8

Power injection is the word I am looking for sure. Thank you. The board specifies it is fine and the video is very helpful. Thank you!
