Steam Frame PCIe USB hub
Edited: Friday 13 November 2026

I wanted two USB-C ports at the front of my Steam Frame so I could try peripherals without running their cables around the headset. I’m designing a board that uses the front PCIe expansion slot and leaves the rear USB-C port free for charging.
