If the power supply is provided to the Raspberry Pi 5 via a power pin or PoE, a PD handshake with the Raspberry Pi 5's USB-C power port cannot be achieved. Therefore, a pop-up window will appear after system startup, as shown in the red box in the image below. | If the power supply is provided to the Raspberry Pi 5 via a power pin or PoE, a PD handshake with the Raspberry Pi 5's USB-C power port cannot be achieved.

Furthermore, the Raspberry Pi 5's USB port will be current-limited to 600mA. At this time, we can plug our PD dongle adapter into the Raspberry Pi 5's power USB-C port '''to achieve 5V5A PD handshake''', and '''the Raspberry Pi 5 will support full-speed operation'''. At the same time, the Raspberry Pi 5's USB current limit will be relaxed '''from 600mA to 1.6A.''' | Furthermore, the Raspberry Pi 5's USB port will be current-limited to 600mA.

<span style="color:red">Note: If a lightning bolt icon appears in the status bar, it's a low voltage warning due to insufficient power supply voltage, not a PD handshake issue, and can be ignored. If you want to remove the lightning bolt icon, you need to replace the power supply to ensure it provides 5.1V to the Raspberry Pi 5.</span> | |||
