PD Dongle

Product Overview

The PD dongle is an adapter for 5V5A PD handshake with a Raspberry Pi 5. It prevents the Raspberry Pi 5 system from displaying a pop-up window, allows the USB port to accept up to 600mA current, supports reversible insertion of the USB-C port, and is compact (only 1*1cm), saving space. It features immersion gold plating and lead-free manufacturing.

Functional Principles and Problems Solved

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.

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.

Applicable Scenarios

Designed for Raspberry Pi 5 powered without using the USB-C port, including:

• PoE Ethernet power supply
• 40Pin GPIO header / pogo pin power supply
• Other 5V power solutions that bypass the USB-C port

Precautions

• The PD dongle is only used for PD negotiation and handshake with the Raspberry Pi 5 and does not participate in power supply itself. The actual power supply capacity is determined by the pins or PoE module itself.
• This product only removes the system-level current limit and does not increase the power of the power supply device itself. If the front-end power supply device cannot provide sufficient current and stable voltage, problems such as system crashes, restarts, and peripheral malfunctions may still occur.
