Internal USB 2.0 expansion for desktop builders

This splitter turns one 9-pin motherboard header into four 9-pin connectors using a short 30 cm cable. It is aimed at system integrators and hobbyists who need extra front-panel or internal USB 2.0 ports without occupying additional headers.

Two small PCB boards and adhesive foam tape

The package includes two 1-to-2 boards that can stay joined or be separated, plus a 30 cm extension cable. Double-sided foam tape lets you secure the boards to the motherboard tray or chassis, and the dual-chip design keeps the signal stable across all four ports.

Check header pin count and physical space

Verify that your motherboard provides a standard 9-pin (10-pin) USB 2.0 header and that the 5 cm by 2.5 cm PCB footprint fits near the header. The 30 cm cable length limits placement to positions close to the motherboard edge.

Questions about this item

Does the foam tape on the splitter boards need replacing after a while?

The boards include double-sided foam tape for mounting on the motherboard or chassis; if the adhesive loses grip over time you can apply fresh tape.

What bandwidth ceiling appears first when all four headers are active?

The single 9-pin USB 2.0 male connection limits total throughput to the USB 2.0 rate shared across the four female headers.

How much heat or noise does the double-chipset board produce during continuous use?

The adapter is passive with no fan; the double chipset draws minimal power and runs silently, adding negligible heat inside the case.
