SKU CH-1SAK-NZGMF

Adds a single 10/100/1000 Mbps RJ45 port via M.2 B & MKey using the Realtek RTL8111H chipset for compact systems

  • Realtek RTL8111H chipset delivers reliable 1Gbps wired networking
  • M.2 B & MKey interface fits miniPC and embedded motherboards
  • Single RJ45 port supports 10/100/1000Mbps autonegotiation
  • Compact M.2 form factor saves PCIe slot space
  • Compatible with Windows, Linux and MAC operating systems

M.2 B & MKey Gigabit NIC

The SMUGDESK M.2 B & MKey Gigabit Ethernet NIC uses a Realtek RTL8111H chipset to add a single RJ45 port to mini PCs and embedded boards. It fits standard M.2 BKey or MKey slots and supports 10/100/1000Mbps autonegotiation for wired networking.

Slot-saving wired upgrade

The card plugs directly into an M.2 PCIe slot, leaving full-size expansion slots free for other add-in cards. Its compact form factor suits space-limited chassis such as soft routers, industrial controllers and small servers. Driver support covers Windows, Linux and MAC operating systems.

For compact system builders

Builders adding wired Ethernet to an M.2-equipped mini PC or embedded board will find this module a direct fit. It does not suit systems lacking an M.2 BKey or MKey slot, nor users needing multi-gigabit speeds or multiple network ports.

Questions about this item

What speed ceiling appears first when the RTL8111H chipset runs at full load?

The Realtek RTL8111H controller tops out at 1000 Mbps, so the gigabit link itself is the first bottleneck under sustained traffic.

How much heat or noise does the card add during all-day operation?

The module has no fan and draws only the power supplied through the M.2 slot, so it runs silently and adds negligible heat inside a miniPC or embedded board.

Which slot must the host board provide for this M.2 B & MKey NIC to function?

The board needs an M.2 slot that accepts both B-key and M-key modules with PCIe signalling; the card plugs directly into that slot and requires no extra cables or brackets.
