More Support

The LRES2041PT-2RJ45 is a dual-port Gigabit Ethernet adapter independently developed by Linkreal Co., Ltd.,based on the Intel® I210 controller. Featuring an M.2 B+M Key interface, it supports stable and reliable 10/100/1000 Mbps network connections. With its PCIe 2.1 x1 interface to the host system, the adapter offers excellent compatibility and low power consumption.

The adapter adopts a modular split design, consisting of two parts: an integrated dual RJ45 network port module,and a compact M.2 2280 (B+M Key) sub-board connected via a dedicated cable. This flexible architecture allowsdeployment in space-constrained or structurally customized system environments.

In addition to delivering high-speed and stable data transmission, the adapter ensures broad compatibility,meeting the stringent demands of industrial automation and embedded systems for real-time performance,stability, and efficiency. It serves as an ideal network connectivity solution for industrial automation, intelligent manufacturing, edge computing, and a wide range of embedded applications.
