Re: Pi5 12v supply


 

开云体育


The best I can tell, the Raspberry Pi 5 *only* supports an input voltage of 5.1V.? It does not support the other USB-PD voltages like 9v, 12v, 15v, etc:

??
?? --
?? Raspberry Pi 5 - 5V/5A, 5V/3A limits peripherals to 600mA
?? --

??
?? --
?? The second is the Raspberry Pi 27W USB-C Power Supply, which provides up to 5A current at +5.1V, and is the recommended supply for Raspberry Pi 5.
?? --


Unfortunately, the documentation leaves some of this up to interpretation:

??
?? --
?? The USB-PD standard allows higher voltages and currents to be negotiated via software but requires an appropriate Power Management Integrated Circuit (PMIC) which is only present on Raspberry Pi 5.
?? --

This link cooberates that any other voltage than 5v is NOT supported:

??
?? --
?? The Raspberry Pi 5 will not negotiate higher voltages (such as 9v or 12v) even though the power supply can provide it to other devices.

Gotta say, this thread has been entertaining. From what I can tell, the RPi5 wants USB-C PD power. The "Official RPi5 Power Supply" provides PD (27W), but is a wall-wart only. The OP I believe wanted something to run from 12V. So...

This takes 9-24VDC in and gives USB-A and USB-C/PD outputs. It is hardwired in to whatever power source you have.

Chargeit! Mini 75W Dual Port USB-A & USB-C PD Charger w/ PPS & QC4.0 Support



This is a cigarette lighter/power point plug in that gives basically the same thing, a USB-A(QC 3.0) and a USB-C(PD) outputs.

USB C Car Charger 5 Pack,


I believe either one of these should power your RPi5. Personally, I think I would go with the CoolGear item as it supports a higher output (75W combined) than the Bangfun (20W) device.

Sheesh haha this group …

??David have you found a 5a PD USB C yet

I have not found one yet - thanks for the tip on the POE hat it’s not 13v but interesting - I could link you to the details I was referencing but - I’m gonna walk on this thread

if I find something I will make sure to post it here we will likely all watch some YouTuber post it at the same time hihi

happy field day all Kelly saying 73
