Description

LRSU3A42-4A is a 4-port USB3.1 host adapter specifically designed for industrial and vision applications. USB3.1 (10Gbps), delivers up to 2 times the data rate over USB 3.0 and is particularly useful for high-speed data storage and imaging devices. It has two independent ASM3142/ASM2142 USB3.1 Host Controllers and x4 PCI Express® Gen3 interface to offer up to 32 Gbps bandwidth for ASM3142/ASM2142. Four USB port devices are connected and working at the same time, which can provide up to 6 Gbps of actual effective bandwidth for each USB port.

In addition to transfer data bandwidth advantage, it features on-board regulated 5V DC power supply 1.5A current limit to supply stable 5V DC power to external USB devices.
Combining high bandwidth, industrial-grade power design and reliable cable connection, it brings convenience to interface USB3.0/USB3.1 devices operating under Windows system and Linux system.
