Power options for RPi + Allo BOSS v1.2
#1
Good Morning,

I've got an RPi 3B+ sitting in front of me, and an Allo BOSS v1.2 arriving tomorrow. I'm trying to determine the prefered way to power the setup, based on the equipment I already own (I may buy a linear power supply in the future, but I don't have one right now):

     Anker PowerCore 10000
     https://www.anker.com/products/variant/P...h/A1263011

     5V 2.4A Switching Power Supply (wall-wart)
     https://www.adafruit.com/product/1995

My options seem to be the following:
     1) Power both from the wall-wart, via the RPi's micro-USB power input.
     2) Power both from the wall-wart, via the DAC's USB-C power input (and a micro-usb-to-usb-c adapter).
     3) Power both from the Anker, via the RPi's micro-USB power input.
     4) Power both from the Anker, via the DAC's USB-C power input.
     5) Power the two separately (with the appropriate jumper removed from the DAC): the RPi via the wall-wart, the DAC via the Anker.

It feels to me as though options 3, 4, and 5 are clearly better, but I'd love some opinions as to which is the best.

Also, if I do choose to power the two separately, it wasn't clear to me what the appropriate power-up and power-down order would be. Ideally it would be essentially simultaneously, but if I'm using a battery for the DAC, there's going to be at least a small delay in time. Am I going to do any damage to the equipment if I power the DAC up first, or vice-versa?

Regards,
William
