SMUGDESK SIPEX24092 4-Port Gigabit M.2 M+B Key Network Card

SKU CH-49Y3-0SG4K MPN SIPEX24092

Adds four gigabit RJ45 ports via an M.2 M+B Key slot for compact multi‑LAN expansion

  • Four RJ45 ports add multi-LAN flexibility
  • M.2 M+B Key fits miniPC and desktop boards
  • Compact M.2 form factor leaves PCIe slots free
  • Industrial-grade stability for routers firewalls and NAS
  • Works with Windows Linux and VMware systems

Four RJ45 ports on an M.2 card

The SIPEX24092 adds four Gigabit Ethernet ports through a single M.2 M+B Key slot. It is built for mini PCs, embedded boards and compact desktops that lack free PCIe slots but need multi-LAN capability for routing, firewall or NAS duties.

M.2 M+B Key slot required

The card only fits motherboards with an M.2 M+B Key connector; it will not work in M-key or B-key only slots. Verify the slot type on your board before purchase, as no adapter is included.

Suits compact network appliances.

Ideal for builders creating soft routers, network monitors or small-form-factor servers where PCIe space is unavailable. Buyers with standard ATX motherboards and open PCIe lanes should consider a conventional multi-port NIC instead.

Questions about this item

What throughput will each of the four RJ45 ports deliver once the card is installed in a mini PC?

Each port auto-negotiates at 10, 100 or 1000 Mbps, giving up to 1 Gbps per connection when the link partner supports it.

Which M.2 slot keying does the SIPEX24092 require and what bandwidth does that interface provide?

The card fits M.2 M+B Key slots, using the PCIe lanes available in that socket for its four gigabit channels.

What physical space and mounting does the M.2 form factor need inside a small-form-factor build?

It occupies a single M.2 slot on the motherboard, requires no extra PCIe bracket and stays within the standard M.2 card outline.
