Unibrain USB 3.2 PCIe Adapter | 20Gbps USB-C, Quad Channel, PCIe Gen3 x8

The Unibrain USB 3.2 Quad-Channel PCIe Host Adapter (SKU 1242) is a high-performance USB expansion card designed to deliver maximum, non-shared USB bandwidth for demanding professional and industrial applications.

Unlike conventional USB PCIe cards that share bandwidth across multiple ports, this adapter provides full 10Gbps performance on each of three USB Type-A ports and up to 20Gbps (USB 3.2 Gen2×2) on a dedicated USB Type-C port, all through a single PCIe Gen3 x8 interface. This architecture ensures consistent throughput for high-speed storage, cameras, data acquisition systems, and other bandwidth-intensive USB devices.

The card is fully backward compatible with USB 3.x and USB 2.0 devices and complies with USB Attached SCSI Protocol (UASP) Revision 1.0, enabling efficient command queuing and improved performance for modern USB storage devices.

Designed for reliability and ease of deployment, the adapter supports USB hot-plug, includes over-current protection and detection on all downstream ports, and powers USB devices directly from the PCIe slot, eliminating the need for auxiliary power connectors.

With broad Windows and Linux support and compliance with CE, FCC, and RoHS standards, the Unibrain USB 3.2 Quad-Channel PCIe Host Adapter is an ideal solution for workstations, servers, and embedded systems requiring uncompromised USB performance.
