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. ?? -- --David KI6ZHD On 01/27/2024 06:49 PM, Michael WA7SKG

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... |
