I’m planning my first “proper” Raspberry Pi project.
I want the end result to be user friendly, and so should use only a single power source.
But internally I need to power several separate devices: the Raspberry Pi 4 itself, as well as two peripherals that have 12v dc barrel type power sources.
After much searching, I’ve not found much detailed information on best practices for powering Raspberry Pi plus peripherals, other than .
Is there any reason why I should not do the following, or is there a better approach?
- Power the project from the mains using a USB-C adapter.
- Connect to a USB-C hub.
- One port on the USB-C hub will power the Raspberry Pi.
- Two ports on the USB-C hub will each use a PD board to deliver 12vdc to the peripherals.
Is there anything I should be checking first to ensure this will work? And is this really a better approach than powering from the GPIO interface?
Thanks for any pointers.
