Thread: Prepping for first Neopixel build clarification about manual

    Default Prepping for first Neopixel build clarification about manual

    I'll be using TCSS parts, and according to the CFX manual it's got LED 1 and 2 going to one negative then 3 and 4 to another (with a bridge). What is the purpose of this bridge (p 107)?

    I've seen some forum goers suggesting a single 22 AWG or dual 26 AWG, am I correct thinking this is one or two physical wires going from point A to B? If yes, does this mean LED 1 gets 2, LED 2 gets 2, LED 3 gets 2 and LED 4 gets 2? Or LED 1 & LED 2 are two wires to a single pad and LED 3 & LED 4 two wires to a single pad on the blade side pcb?

    You can use the led driver negatives to fully kill power to the pcb when the blade is not lit...I just combine the negatives to the board negative and use kill keys. The dual wires are to manage high current draw from the led strip, and the general consensus seems to be what you wrote.
