Microconnect MC-M.2-A+E-RTL8125B-S - Network interface card

The Microconnect MC-M.2-A+E-RTL8125B-S is an M.2 A+E network adapter that provides 2.5G Ethernet connectivity for PCs. It connects directly to an M.2 A+E slot on the motherboard, offering a stable, wired connection without occupying a full-sized PCIe expansion slot. By using a wired interface, it avoids potential wireless interference and supports data transfer speeds of up to 2500 Mbit/s. This 2.5 Gigabit connection provides greater bandwidth for network-intensive tasks than standard gigabit Ethernet.

Powered by a Realtek RTL8125B chipset, the card is suited for compact desktop or embedded systems. Weighing 80 grams, it is designed for environments where space is limited. As it functions exclusively as a wired network interface, the module does not include Wi-Fi or Bluetooth radios. It is compatible with Windows 10 and 11, Linux kernel 5.x and newer, and FreeBSD.

• Single RJ45 Ethernet port supporting 10, 100, 1000, and 2500 Mbit/s link rates
• Compliant with IEEE 802.3, 802.3u, 802.3ab, and 802.3bz standards
• Supports Wake-on-LAN for remote system activation
• VLAN tagging for network traffic segmentation
