LORDWORLD ETH/USB HUB HAT B Expansion Board 3 USB 2.0 1 RJ45 10/100M

SKU CH-FZKP-N63X1

Adds one RJ45 10/100M Ethernet port and three USB 2.0 ports to Raspberry Pi boards via pogo pins or USB cable

  • Adds wired networking with 10/100M RJ45 port
  • Three extra USB 2.0 ports for peripherals
  • Pogo pins connect directly to Pi Zero boards
  • USB hub cable links Pi 4B 3B+ 3A+ 2B
  • RTL8152B chip handles Ethernet and USB hub functions

ETH/USB HUB HAT B Expansion Board

The LORDWORLD ETH/USB HUB HAT B is an expansion board that adds one RJ45 Ethernet port and three USB 2.0 ports to compatible Raspberry Pi models. It uses a pogo-pin connector for direct attachment to Pi Zero variants and a USB HUB connector with cable for Pi 4B, 3B+, 3A+ and 2B. The onboard RTL8152B chip provides 10/100M auto-negotiation.

Makers adding wired Ethernet and extra USB ports

This board suits makers who need a single 10/100M wired network link and three additional USB 2.0 ports on a Raspberry Pi Zero, 2B, 3A+, 3B+ or 4B. It is not for builders who require Gigabit Ethernet speeds, USB 3.0 bandwidth, Power-over-Ethernet capability or more than three downstream USB ports.

RTL8152B chip with 10/100M Ethernet

The RTL8152B Ethernet controller delivers one RJ45 port with 10/100M auto-negotiation, which determines the maximum wired network throughput. The three downstream ports operate at USB 2.0 and 1.1 speeds, so connected peripherals share that bandwidth ceiling.

Highlights

  • Adds wired networking with 10/100M RJ45 port
  • Three extra USB 2.0 ports for peripherals
  • Pogo pins connect directly to Pi Zero boards
  • USB hub cable links Pi 4B 3B+ 3A+ 2B
  • RTL8152B chip handles Ethernet and USB hub functions

Questions about this item

Will the three USB 2.0 ports share one 2.0 bus when the HAT is plugged into a Pi 4 B?

Yes. The hub connects through a single USB 2.0 link, so all three ports share that 2.0 bandwidth.

What practical speed can the RJ45 port deliver on a Pi Zero 2 W?

The RTL8152B chip negotiates at 10 or 100 Mbit, so real-world throughput tops out at 100 Mbit regardless of the Pi model.

Does the board need a USB cable to work with a Raspberry Pi 3 B+?

Yes. A USB HUB connector is provided for Pi 4B, 3B+, 3A+ and 2B, so a cable is required for those models.
