Vszerda N37472-3 10/100/1000 Mbps network card

M.2 B-Key M-Key Gigabit Ethernet Adapter

This Vszerda network card converts an M.2 B-Key or M-Key slot into a single RJ45 port using the Realtek RTL8111H chip. It delivers wired Ethernet at 10, 100 or 1000 megabits per second for desktop systems. The package includes a 30 centimetre cable, the adapter card and an instruction sheet. The unit weighs approximately 120 grams and uses thick gold-plated contacts for stable connection.

Suited for desktop builders adding a wired port

The card supports Windows 7, 8, 10 and Windows Server 2008R2, 2012, 2016 and 2019, plus Linux kernels from 2.6.31 up to 4.11 LTS releases. It is not intended for users needing multi-gigabit speeds, multiple Ethernet ports or Wi-Fi and Bluetooth functionality. Builders without an available M.2 B-Key or M-Key slot cannot install this adapter.

Single RJ45 port at 1000 megabits per second

The decisive specification is the single gigabit Ethernet port provided by the RTL8111H controller. If your project requires 2.5 or 10 gigabit throughput, a second network interface, or a different slot type such as PCIe x1, this card will not meet the requirement. Verify M.2 key compatibility and operating-system support before purchase.
