Compact M.2 Gigabit NIC for small systems

The Vszerda M.2 A+E Key Gigabit Ethernet network card adds a wired 1000BASE-T connection to devices with a compatible M.2 slot. It is designed for micro, mini and thin computers where internal space is limited. The module measures 1.25 in by 0.75 in by 0.5 in and installs directly onto the board.

Suits builds with an M.2 A+E slot.

This card fits systems that expose an M.2 A+E key interface for networking expansion. Buyers whose device lacks that specific slot, or who need multi-gigabit speeds beyond 1 Gbps, should look at a different solution. The feature set targets IEEE 802.3, 802.3u and 802.3ab compliance with VLAN and jumbo-frame support.

M.2 A+E key interface decides fit

The single specification that determines compatibility is the M.2 A+E key interface. Without that exact slot the module cannot be installed, regardless of other hardware details. The card supports checksum offload, segmentation task-offload and IEEE 802.1Q VLAN tagging through that connection.

Questions about this item

Which M.2 key does this Gigabit Ethernet card use and what form factor fits?

The card uses an M.2 A+E key and measures 1.25 in by 0.75 in by 0.5 in, so it fits small-form-factor systems with that slot.

What real-world throughput can I expect from the 1000BASE-T rating?

The 1 Gbps link supports full-duplex flow control and jumbo frames up to 9K bytes, giving near-wire speeds on a standard Cat5e or better cable.

Does the M.2 interface limit the 1 Gbps Ethernet speed in practice?

The M.2 A+E connection carries the 1000BASE-T signal without bottleneck, and the controller handles IEEE 802.3x flow control and checksum offload at line rate.
