I saw that i could use and external power supply to power the leds and also another device suck as a pi with one power source. “It is convenient that the power wires are duplicated on the input side because you can connect the auxiliary power wires to your 5 V power supply and then the power will be available on the data input connector and can be used to power the microcontroller that is controlling the LED strip. This means you can power the microcontroller and LED strip from a single supply without having to make branching power connections.”
I was wondering if i could get a wiring diagram. Wasnt sure if i could run the power source, 5v to the aux power, cut off the jst connector and attatch the positive and negative to a usb to supply power to the pi, and connect the data line to the gpio pin. The leds and pi theoretically would be both grounded together so i shouldnt need to use a ground gpio pin or would i have to do that as well? That is, if what i said above is what you would do. Just trying to avoid having to plug two thi gs in seeing the leds and pi both use 5v
Thanks,
