Dual USB-C adapter for internal 2.0 headers

This Fervit adapter converts a single motherboard 9-pin or 10-pin USB 2.0 header into two external USB-C female ports. It is intended for builders who want front-panel USB-C access without a native header. The device operates purely as a USB 2.0 passthrough.

480 Mbps data and 500 mA power limit

The adapter delivers USB 2.0 speeds of 480 Mbps and supplies up to 5 V at 500 mA per port. It handles keyboards, mice, flash drives and similar peripherals comfortably. It cannot support USB-C Power Delivery, video output or audio functions, so it is unsuitable for charging laptops or driving displays.

PCBA construction with dual Type-C sockets

The unit is built on a compact printed circuit board with two USB 3.1 Type-C female connectors. It plugs directly into a standard 9-pin or 10-pin internal header and requires no extra drivers. The design adds two reversible ports to a chassis while leaving the internal header occupied.
