Connectivity Expansion

This LetLinkSo adapter converts an M.2 PCIe NVMe socket into an OCuLink SFF-8611 4i host port using a 15 cm flexible printed circuit board. It supports PCIe 4.0 x4 bandwidth up to 64 Gbps at 16 GT/s per lane and remains backward compatible with PCIe 3.0 and 2.0 systems.

Builder Fit

Suits owners of laptops or mini PCs who need external GPU, U.2 SSD or PCIe card connectivity through their existing M.2 slot. Not for users whose device lacks an M.2 PCIe NVMe socket or who require hot-swap capability, as the installation requires a full power-off.

Ready Install

The package includes a screwdriver and fixing screw so the board can be secured immediately after trimming the 22×80 mm NVMe board to 2230, 2242, 2260 or 2280 lengths. Driver-free operation works with Windows, Mac OS and Linux for instant recognition.

Questions sur cet article

What must my laptop or mini PC already have for this M.2 to OCuLink adapter to work?

Your device needs an M.2 PCIe NVMe socket (2230, 2242, 2260, or 2280) with an available 22×80 mm slot; the board can be trimmed to 22×30 mm, 22×42 mm, or 22×60 mm if space is tight.

Will this card still function if my system only supports PCIe 3.0 or 2.0?

Yes, the adapter is backward compatible with PCIe 3.0 and 2.0, so it will operate at the lower generation speed while keeping the same OCuLink SFF-8611 4i host port.

How can I verify the link is running at PCIe 4.0 x4 after installation?

Check your OS device manager or a tool like GPU-Z; the OCuLink port should negotiate a 16 GT/s per lane link (64 Gbps total) when connected to a PCIe 4.0 eGPU or SSD.
