Expansion HAT for Raspberry Pi

The WaveShare Ethernet USB Hub HAT adds one RJ45 10/100M port and three USB 2.0/1.1 ports to a Raspberry Pi single-board computer. It is built around the RTL8152B Ethernet chip and includes status LEDs for power, network link and each USB port. The board targets makers and developers who need extra wired connectivity and peripheral expansion for embedded projects.

Makers needing wired Ethernet and extra USB

This HAT suits builders who want a stable wired network link without relying on the Pi’s onboard Ethernet or Wi-Fi, and who also need more USB ports for sensors, storage or input devices. It is not for users who require Gigabit Ethernet speeds, USB 3.0 bandwidth or Power-over-Ethernet capability, because the hardware provides only 10/100M Ethernet and USB 2.0/1.1 interfaces.

RTL8152B 10/100M Ethernet controller

The single specification that decides fit is the RTL8152B chip, which limits the RJ45 port to 10/100M throughput and the three downstream ports to USB 2.0/1.1 data rates. If your application demands higher network bandwidth or faster USB transfers, this HAT will not meet those requirements.

Questions about this item

Which Raspberry Pi models can I connect this HAT to?

It fits Raspberry Pi 4B, 3B+, 3B, 2B, Zero, Zero W and Zero 2W boards.

Will the Ethernet port slow down if I also use the three USB ports?

The RJ45 link runs at 10/100M and the USB ports share USB 2.0 bandwidth, so combined traffic stays within those limits.

How do I know the board is powered and the ports are active after I attach it?

Onboard LEDs show power, Ethernet link and activity for each of the three USB ports.
