LORDWORLD Raspberry Pi Zero 2W to 3B Adapter development board

SKU CH-6AS7-4WJPN

Adapter board lets a Raspberry Pi Zero 2W plug into a Raspberry Pi 3B or 3B+ footprint, adding four USB 2.0 ports, 10/100 Ethernet via RTL8152B, a headphone jack and a speaker header

  • Adds four USB ports for peripherals using 2.0 and 1.1 speeds
  • Wired network access via RTL8152B chip at 10 and 100 M
  • Audio output through headphone jack extended from USB plus speaker header
  • Pogo pins let you mount a Zero 2W without soldering
  • Matches Raspberry Pi 3B and 3B+ board interfaces for drop-in use

Adapter for Zero 2W to 3B Migration

This adapter board lets a Raspberry Pi Zero 2W replace a Raspberry Pi 3 Model B or B+ in existing projects. It bridges the smaller module to the larger board's full-size interface layout. Makers can upgrade compute performance without redesigning enclosures or wiring. The first-generation Zero is not supported by this board.

Thermals and Power in Normal Use

The RTL8152B Ethernet chip and four USB 2.0 ports draw modest power during typical I/O tasks. No active cooling is present on the adapter itself, so the Zero 2W module relies on its own thermal characteristics. Audio output via the onboard headphone jack and speaker header adds negligible load. Power consumption stays low for edge-device workloads.

Behaviour Under Sustained Load

Under continuous network traffic the 10 / 100 M Ethernet link and USB 2.0 / 1.1 ports maintain steady throughput without thermal throttling on the adapter. The pogo-pin connection remains mechanically secure during extended operation. No onboard voltage regulation or heatsinking is provided, so sustained CPU load on the Zero 2W must be managed by the module's own design.

Questions about this item

How do I install the Pi Zero 2W onto the adapter without soldering?

Align the Zero 2W with the pogo-pin array and press down firmly until the pins seat; the board then matches the 3B/3B+ footprint.

Will the onboard RTL8152B Ethernet chip or USB hub need firmware updates or replacement?

The RTL8152B and USB 2.0/1.1 hub are fixed-function silicon with no user-serviceable firmware; no scheduled replacement is required.

What throughput ceiling appears first when the Gigabit Ethernet port runs sustained traffic?

The RJ45 port is 10/100 M adaptive, so the 100 Mbit/s link caps throughput before the USB 2.0 bus does.
