Ethernet and USB HAT for Raspberry Pi

This HAT expansion board adds a wired RJ45 Ethernet connection and three USB ports to compatible Raspberry Pi models. It is built around the RTL8152B Ethernet chip and draws power from the Pi’s 5 V supply. The compact 65 mm by 30 mm footprint matches the Zero form factor and includes 3.0 mm mounting holes.

Makers needing wired networking and extra USB ports

Developers who require a stable 10/100M Ethernet link or additional USB 2.0 connections for peripherals will benefit from this board. Builders who need Gigabit Ethernet speeds or USB 3.0 bandwidth should look at alternative solutions that provide those higher specifications.

RTL8152B chip provides 10/100M Ethernet

The onboard RTL8152B controller delivers a single RJ45 port operating at 10/100M, which determines the maximum wired network throughput. Three downstream USB ports share USB 2.0 and 1.1 compatibility for keyboards, mice, storage or other accessories.

Questions about this item

Will the RTL8152B Ethernet chip or the three USB 2.0 ports need any periodic replacement?

The board has no moving parts and no user-serviceable components, so the RTL8152B chip and the three USB 2.0 ports do not require scheduled replacement under normal use.

What is the throughput ceiling of the RJ45 10/100M port when the board runs continuously?

The RJ45 port is rated at 10/100M, so sustained traffic will top out at 100 Mbit/s regardless of how long the board operates.

How much heat or fan noise does the 5 V powered HAT produce during all-day operation?

The HAT draws power from the Pi’s 5 V rail, has no onboard fan, and runs silently; any warmth stays within the normal operating range of the Raspberry Pi itself.
