LORDWORLD Raspberry Pi Zero to 3B Adapter development board

SKU CH-7X8Z-X4H6W

Adapts a Raspberry Pi Zero to fit Raspberry Pi 3B or 3B+ boards, adding four USB 2.0 ports and a 10/100 M Ethernet port via RTL8152B chip

  • Drop-in replacement for Raspberry Pi 3B/B+ using a Pi Zero
  • Zero attaches securely via purpose-built connectors
  • GPIO header matches 3B height for direct HAT compatibility
  • Four USB ports operating at USB 2.0 and 1.1 speeds
  • Wired network via RTL8152B chip at 10/100 M adaptive

Pi Zero form-factor adapter

This board lets a Raspberry Pi Zero occupy the footprint of a 3B or 3B+ unit. Makers upgrading legacy projects can swap the larger board without redesigning enclosures or mounting points. The GPIO header sits at the 3B height so existing HATs align mechanically and electrically. It targets developers who need the Zero’s compact compute in a 3B-compatible layout.

Build integration and freedoms

The adapter supplies four USB 2.0/1.1 ports and a single RJ45 jack driven by an RTL8152B chip at 10/100 M speeds. A Pi Zero mounts on the custom connectors, adding wired networking and extra USB endpoints that the Zero lacks natively. This removes the need for separate hub or Ethernet dongles in a 3B-sized project. Power and data route through the adapter so the Zero becomes a drop-in replacement.

Bundled hardware impact

No cables, headers or software media are included in the package. The onboard USB and Ethernet controllers are functional immediately once a Pi Zero is seated and the system boots a compatible OS image. Users must provide their own Pi Zero module, power supply and any HATs required for the application. The board itself adds no programmable logic or firmware beyond the RTL8152B interface.

Questions about this item

Will the four USB 2.0 ports and the 10/100 M Ethernet handle all-day data traffic without throttling?

The board provides four USB 2.0 ports and a single 10/100 M RJ45 port driven by the RTL8152B chip; sustained throughput stays within those interface limits.

Does the adapter add audible fan noise or noticeable heat when the Pi Zero runs continuously?

The adapter itself has no fan and no active cooling; any heat or noise comes only from the attached Pi Zero module.

Which Pi Zero variant and 40-pin HATs must I already own for this board to work?

You need any Raspberry Pi Zero with a 40-pin header and any HAT designed for the Pi 3B/3B+ 40-pin GPIO layout.
