LORDWORLD Mini Dual Gigabit Ethernet Base Board for Raspberry Pi CM4 40PIN GPIO

SKU CH-ZRS7-HW98S

Compact base board adds dual Gigabit Ethernet, microSD and USB to a Raspberry Pi CM4 via 40-pin GPIO

  • Dual Gigabit Ethernet enables redundant network paths
  • Standard CM4 socket accepts Lite and eMMC modules
  • 40-pin GPIO header exposes all CM4 I/O
  • Onboard micro SD slot provides boot storage
  • Compact form factor suits embedded integration

Compact Base Board for Raspberry Pi CM4

The LORDWORLD Mini Dual Gigabit Ethernet Base Board provides a standard CM4 socket and a 40PIN GPIO header in a compact form factor. It is designed for developers evaluating the Compute Module 4 Lite or eMMC variants and for integrators embedding the module into finished products. Onboard Ethernet, microSD and USB interfaces deliver essential connectivity for industrial and IoT edge applications.

Target users and limitations

This board suits engineers who need dual Gigabit Ethernet ports, a microSD slot and USB access alongside full GPIO exposure for custom hardware development. It is not for buyers who require built-in wireless connectivity, additional high-speed storage interfaces or a larger selection of native display outputs. Users planning to operate without a separate Compute Module 4 should also look elsewhere.

Deciding specification

The defining feature is the dual Gigabit Ethernet implementation on a miniature carrier that still breaks out the full 40PIN GPIO header. If a project demands two wired network links in a space-constrained enclosure this board matches the requirement; if only a single Ethernet port is needed a simpler carrier may be more appropriate.

Questions about this item

How do I verify the dual Gigabit Ethernet ports are working after I install the CM4 module?

Connect each RJ45 port to a live network link and confirm both interfaces appear in the CM4 operating system with link lights active.

What comes in the box and which essential parts must I source separately?

The board ships with the 40PIN GPIO header and dual RJ45 connectors fitted; you must supply a Compute Module 4 Lite or eMMC module and a Micro SD card.

Which Compute Module 4 variant should I choose for this base board?

Both CM4 Lite and eMMC versions are supported; pick Lite if you prefer booting from the onboard Micro SD slot, or eMMC for integrated storage.
