The Ugreen 30775 (US230) is a hybrid PCI Express expansion card combining **3 USB 3.0 ports** with a **Gigabit Ethernet (RJ45) port** on a single PCB. It’s ideal for desktops that need both extra high-speed USB ports and wired network connectivity, especially in scenarios such as desktop PCs without built-in network ports or with limited USB 3.0 capacity.
This card supports USB 3.0 transfer rates up to 5 Gbps (backward compatible with USB 2.0 / 1.1), powered via the motherboard plus optional SATA power for stability under heavy USB load. The Gigabit LAN port supports 10 / 100 / 1000 Mbps speeds with support for jumbo frames and VLAN tagging.
With both USB and network upgrades in one card, installation is easy: insert into a PCIe x1 (or larger) slot, optionally connect SATA power, install drivers if needed, and enjoy expanded I/O without cluttering your motherboard with multiple add-on cards.
