Overview The PCIe TO 2.5G ETH Board (C) is a compact PCIe to 2.5G Ethernet adapter designed specifically for Raspberry Pi 5. By using the native 16-pin PCIe x1 Gen2 interface, this 2.5G bE RJ45 LAN board gives your Rasp-berry Pi 5 a high-speed wired network upgrade that is perfect for NAS, router, firewall and home lab applications. Built around the original Realtek RTL8125 controller, the PCIe to 2.5G Ethernet board supports 10/100/1000/2500 Mbps link rates for smooth 2.5G bE networking. Compared with standard Gigabit Ethernet, this PCIe 2.5G network card offers higher bandwidth and lower latency, ideal for file servers, media streaming, backups and 2.5G switches that demand more throughput from your Pi-based projects.
For ease of use, the PCIe TO 2.5G ETH Board (C) is driver-free under Rasp-berry Pi OS. Just connect the included 16-pin PCIe cable between the expansion board and the Pi 5, power on, and the 2.5G Ethernet adapter will be detected automatically as a standard RTL8125 PCIe network card. No extra drivers, scripts or kernel patches are required for plug and play operation. The hardware layout is optimized for compact builds. A transparent acrylic mounting plate and side-mount design keep the 2.5G Ethernet port to the side of Rasp-berry Pi 5, saving vertical space above the board for coolers or other HATs.
Power is supplied directly via the PCIe cable by default, keeping wiring simple, while onboard LEDs clearly show link and activity status on the RJ45 port. Whether you are building a small NAS, a 2.5G router, an edge gateway, a home lab cluster or an industrial control node, this PCIe to 2.5G Ethernet adapter board (C) gives your Rasp-berry Pi 5 a reliable 2.5G bE RJ45 port with PCIe x1 Gen2 performance, driver-free setup and a space-saving side-mount acrylic bracket.
