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

This product is suitable for scenarios where 5V power supply is required and the Raspberry Pi 5 5V5A PD handshake cannot be triggered, including but not limited to:

PoE Ethernet power supply
GPIO header/pin power supply
5V power module, battery-powered module power supply
and other non-standard USB-C PD 5V power supply solutions.

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.
