SMUGDESK PoE Ethernet USB Hub HAT for Raspberry Pi Zero 2W/Zero W

SKU CH-N20B-DA2JE

Adds wired 10/100 Mbps Ethernet and extra USB 2.0 ports to a Raspberry Pi Zero 2W or Zero W while powering it through a single PoE cable

  • IEEE 802.3af PoE delivers power and network over one RJ45 cable
  • RTL8152B chip provides 10/100Mbps wired Ethernet for stable low-latency connectivity
  • Multiple USB 2.0 Type-A ports expand Pi Zero for flash drives and peripherals
  • Fully isolated SMPS circuit supplies 5V 2.5A safely with plug-and-play operation
  • Designed specifically for Raspberry Pi Zero 2W and Zero W via pogo pin docking

PoE HAT for Raspberry Pi Zero

This PoE HAT adds wired Ethernet and extra USB ports to Raspberry Pi Zero 2W and Zero W boards. It draws power and data through a single RJ45 cable using the IEEE 802.3af standard, removing the need for a separate power supply. The onboard RTL8152B chip provides 10/100Mbps network speeds, while multiple USB 2.0 ports let you attach storage, cameras or sensors. The pogo-pin connection makes installation quick and driver-free.

Suits remote or embedded deployments

Builders who need a tidy, single-cable setup for headless Pi Zero projects will benefit from the combined power and Ethernet link. The USB hub expands the board’s limited I/O for peripherals such as flash drives or relay modules. Buyers who require gigabit Ethernet throughput should look elsewhere, as the controller is limited to 100Mbps. Projects that must run on battery power or Wi-Fi alone are not addressed by this HAT.

10/100Mbps Ethernet via RTL8152B

The RTL8152B controller delivers 10/100Mbps wired networking over a standard RJ45 jack. This speed ceiling is the key specification that decides whether the board fits your application. If your project demands higher bandwidth, this HAT will not meet that requirement.

Questions about this item

Will the 2.5 A PoE output power both the Raspberry Pi Zero 2W and devices plugged into the USB 2.0 ports?

Yes, the isolated SMPS circuit delivers 5 V at 2.5 A through the pogo pins, which is enough for the Pi Zero 2W plus typical USB 2.0 peripherals such as flash drives or sensors.

How can I confirm the RTL8152B Ethernet chip has negotiated a 100 Mbps link after I connect the RJ45 cable?

The RJ45 port LEDs will show a solid link light and a blinking activity light when the 10/100 Mbps auto-negotiation completes successfully.

Does the HAT package include the pogo pin header and mounting hardware, or must I buy them separately?

The board ships with the pogo pin docking array already fitted; you only need to supply a Raspberry Pi Zero 2W or Zero W and a PoE-capable Ethernet cable.
