All,
I have bought some landscape cable (This one) to run for power injection for about 250 5v nodes. I have seen others post about 6core 14/020 Security cable (Like this one) (with 2 or 3 wires each for power and data or just power) which seems to be a cheaper option and I was wondering what would be better accounting for Amps and Voltage Drop.
Also, I am not a guru on electronics. I see there is a standard or running +ve and -ve for power injection (e.g. at the end of the string) but was wondering why the -ve is needed (as I would assume due to LEDS being diodes, the return would be covered through the string itself. Haven't tested without but just wondering for my own learning.
Cheers
