Expand four USB 3.2 Gen1 ports via PCIe x1 slot with Renesas controller.
Connecting multiple high-speed peripherals in industrial automation or server environments often exhausts native USB ports, creating bottlenecks for data acquisition devices. The LRSU9A71-4A(3U) PCIe USB adapter solves this by expanding connectivity without occupying valuable external hubs.
Powered by the Renesas uPD720201 controller, this card provides four USB 3.2 Gen1 Type-A ports with a shared bandwidth of up to 5Gb/s. This ensures consistent data throughput for connected devices, enabling reliable operation of industrial cameras and storage drives simultaneously while maintaining backward compatibility with USB 2.0 standards.
Ideal for machine vision systems and data centers requiring robust peripheral expansion, this adapter fits into any PCIe x1, x4, x8, or x16 slot. Its compact design and broad OS support, including Windows Server and Linux variants, make it a versatile solution for enhancing system I/O capacity efficiently.
Based on Renesas uPD720201 master control solution for stable performance.
Expands 4 USB 3.2 Gen1 ports via a single PCIe x1 slot.
