LORDWORLD M-Key to CFexpress Type-A Adapter

SKU CH-F1AE-11RGP

Adapts a CFexpress Type-A card to an M.2 M-key NVMe slot with PCIe 4.0 gen4x2 bandwidth and gold-plated connectors

  • Connect CFexpress Type-A cards to M.2 M-key slots for expanded storage options
  • Achieve full CFexpress B specification speeds via PCIe 4.0 gen4x2 bandwidth
  • Gold-plated connectors and precision PCB ensure reliable high-frequency signal transmission
  • Differential signal layout eliminates CAF micro short circuits and signal attenuation
  • Adapter designed specifically for CFexpress Type-A — not compatible with XQD cards

M-Key to CFexpress Type-A Adapter

This adapter connects a CFexpress Type-A card to an M.2 M-Key NVMe slot. It enables cameras or card readers to use the slot as a host interface for the memory card. The design targets users who need to extend CFexpress storage into an NVMe connector. It does not function with XQD cards.

Compatibility and limits

The adapter suits builders or technicians adding CFexpress Type-A support to an M.2 NVMe host. It will not work for XQD card formats or for M.2 slots that lack NVMe signalling. Buyers who need XQD compatibility or a different host interface should look at other solutions.

Sustained signal integrity

Gold-plated connectors and a precision PCB with differential signal layout reduce parasitic capacitance and inductance. The design avoids CAF micro short circuits to maintain high-speed data transmission under continuous load. Bandwidth runs at PCIe 4.0 gen4x2, supporting CFexpress B specification full speed.

Questions about this item

Does my motherboard need an M.2 slot wired for NVMe PCIe 4.0 to use this adapter?

Yes, the adapter plugs into an M.2 M-key slot that carries an NVMe PCIe 4.0 x2 link so the CFexpress Type-A card can run at its rated bandwidth.

Will this adapter also accept the XQD cards I already own?

No, the adapter is designed only for CFexpress Type-A cards and will not work with XQD media.

How can I verify the adapter is delivering PCIe 4.0 speeds after installation?

Check the negotiated link width and speed in your system BIOS or with a hardware-info utility; it should report a PCIe 4.0 x2 connection when a CFexpress Type-A card is seated.
