LORDWORLD PCIe to USB 3.2 Gen1 Adapter for CM4 IO Board 4 Ports VL805

SKU CH-WRJN-9AH8S

Adds four USB 3.2 Gen1 ports to a Compute Module 4 IO board using a VL805 controller with driver-free operation

  • Designed for Raspberry Pi Compute Module 4 IO Board
  • Four USB 3.2 Gen1 ports with USB 3.0 / 2.0 / 1.1 compatibility
  • Powered from PCIe 12V or 12V DC header
  • Onboard VL805 chip for driver-free plug-and-play operation
  • PCIe extension cable recommended when connecting to a PC motherboard

PCIe to USB 3.2 Gen1 Adapter for CM4 IO Board

This adapter adds four USB 3.2 Gen1 ports to a Raspberry Pi Compute Module 4 IO Board. It targets developers and makers who need extra high-speed connectivity for peripherals, storage or test equipment. The onboard VL805 controller operates without drivers for plug-and-play simplicity.

Four USB 3.2 Gen1 ports with backward compatibility

The card delivers four ports that run at USB 3.2 Gen1 speeds and remain compatible with USB 3.0, 2.0 and 1.1 devices. Power can be drawn from the PCIe 12 V rail or from an onboard 12 V DC header, giving flexibility for different carrier boards. Bandwidth is shared across the four ports, so simultaneous heavy transfers will contend for the single PCIe lane.

Upgrades the CM4 IO Board's native USB count

The CM4 IO Board provides only one native USB 2.0 port; this adapter expands that to four USB 3.2 Gen1 ports for cameras, SSDs or debug tools. The jump is worthwhile when a project needs multiple high-speed devices or when the single native port is already occupied. It is not suited for builds that require more than four ports or that lack a free PCIe slot and 12 V supply.

Questions about this item

Will this adapter work with the 12 V supply on my existing CM4 IO Board?

Yes, it draws 12 V directly from the PCIe slot or from the IO Board's 12 V DC header.

How can I confirm the VL805 controller is active after I plug it in?

The four USB 3.2 Gen1 ports will enumerate immediately — driver-free, plug-and-play — so any connected device should appear in lsusb or Device Manager.

Does the package include a PCIe extension cable for motherboard installation?

No, only the adapter board is supplied; a PCIe extension cable must be purchased separately if you plan to use it in a PC motherboard slot.
