Dual 2.5G M.2 B+M Key Ethernet NIC, Dual-Port 2.5GBase-T M.2 Network Expansion Card

This dual 2.5-gigabit M.2 Ethernet expansion card adopts M.2 B+M universal key design, utilizing spare M.2 slots on compact motherboards to expand two independent 2.5GBase-T wired network ports, ideal for small devices without extra PCIe expansion space.

Each RJ45 port supports auto speed switching among 100Mbps, 1000Mbps and 2500Mbps, meeting high-bandwidth demands of multi-network routing, storage transmission and industrial data acquisition. It supports link aggregation to superpose dual-port bandwidth and network failover to prevent service interruption.

Built-in hardware checksum offload reduces CPU occupancy under high concurrent traffic; it also carries advanced functions including VLAN partition and Wake on LAN remote management. Slim low-power structure fits mini ITX chassis, soft routing gateways and embedded industrial control equipment, with optimized anti-interference wiring to lower packet loss and latency.

Compatible with mainstream desktop, server and virtualization operating systems, it is a space-saving dual multi-gigabit network upgrade solution for mini PCs, home NAS, firewalls and industrial monitoring terminals.
