Dual-port USB 3.1 Type-A host adapter for PCIe expansion.
Expanding legacy or specialized USB peripheral connectivity in modern servers often requires reliable, high-bandwidth host adapters that fit compact chassis. The LRSU3A42-2A addresses this need by providing dual USB 3.1 ports via a single PCIe slot, ensuring stable connections for industrial automation equipment or data acquisition devices without occupying valuable external panel space.
Equipped with the ASM3142 I/O controller and a PCIe 3.0 x4 interface, this adapter delivers robust throughput for simultaneous device operations. The dual internal USB Type-A connectors allow direct cabling to backplanes or internal hubs, simplifying cable management in 2U and 3U metal cases while maintaining full USB 3.1 performance standards for connected peripherals.
Ideal for embedded systems, digital signage, and industrial PCs requiring internal USB expansion, the LRSU3A42-2A supports Windows XP through Server 2012. Its low-profile design and broad OS compatibility make it a versatile solution for integrating USB devices into space-constrained computing environments efficiently.
Provides two internal USB Type-A connectors for connecting peripherals directly inside the chassis.
Powered by the ASM3142 I/O controller for reliable USB 3.1 performance and stability.
Utilizes PCIe 3.0 x4 bandwidth, compatible with x8 and x16 slots for flexible installation.
Low-profile form factor (106mm x 56mm) suitable for 2U and 3U metal cases.
