LORDWORLD PCIe to USB 3.2 Gen1 HAT for Raspberry Pi 5 development board

Expansion for Raspberry Pi 5

This HAT adds four USB 3.2 Gen1 ports to the Raspberry Pi 5 through its 16-pin PCIe interface. It is aimed at developers and makers who need more high-speed peripheral connections than the board provides natively. The driver-free design means it works immediately on supported operating systems.

Build integration and cooling

The board connects via a 16-pin cable to the Pi 5’s PCIe connector, leaving the GPIO header free for other HATs or sensors. An onboard power monitoring chip and EEPROM allow software control of each USB port’s power state. A reserved airflow vent lets you add a cooling fan to keep the Pi 5 running stably under sustained loads.

Capacity and limits

Four USB 3.2 Gen1 ports give enough bandwidth for multiple storage drives, cameras or other high-speed devices at the same time. The PCIe link itself is the bottleneck, so total throughput across all ports cannot exceed the single-lane Gen 3 ceiling. Users needing more than four ports or higher aggregate bandwidth will need a different approach.
