Would it be possible to use a multi-core cable to have power and data in the same wire?
I'm using WS2815 LEDs. The total current needed is 9.6A. For a cable of 8 meters, a 2.5mm wire is needed. Because of the distance between the microcontroller and the first LED I am planning to use a MAX485.
Could I use a four core 2.5mm2 cable to transport the needed power (12V and ground) and data (data A and data B,) or is there a high chance of interference on the data lines because of the 12V at 9,6A (almost 120W) in the same cable.
