【Efficient M.2 2280 B+M Key 5G Ethernet Adapter】
The M.2 to 5G Ethernet Network Card converts your M.2 B+M Key slot into a high-speed 5G Ethernet RJ45 port. Powered by the Realtek RTL8126 chipset, this network card delivers up to 5Gbps adaptive data rates, providing superior performance for demanding network environments. It is the perfect solution for upgrading your desktop, mini PC, NAS, or embedded system without occupying a full PCIe slot.
【Key Applications】

• Gaming PC Upgrade – Eliminate lag with low-latency 5G wired connection, 5x faster than standard Gigabit Ethernet. No more wireless interference or packet loss.
• DIY NAS / Home Server – Add a high-speed Ethernet port to your TrueNAS, Unraid, or Synology setup for fast file transfers and media streaming.
• Mini PC & SFF Builds – The M.2 2280 form factor fits perfectly into space-constrained systems like Intel NUC, LattePanda, Beelink, and more.
• Raspberry Pi 5 Networking – Use with an M.2 HAT to give your Pi 5 a 5Gbps Ethernet interface—ideal for router, firewall, or network appliance projects.
• Industrial / Embedded Systems – Wide operating temperature (0~70°C) and low power consumption (1.7W) make it reliable for factory automation, digital signage, and IoT gateways.
• Thin Client / Diskless Workstation – PXE boot support enables network booting and centralized OS deployment for offices, labs, and Internet cafes.
