From the project
USB 2.0 hub with MTT & per port power control
Production files (JLCPCB): gerbers BOM POS
This repository contains the KiCad and OpenScad files for a USB 2 Hub with per-port power and MTT.
The PCB design contains 4 USB-A ports and 1 USB-C port. The latter is used to connect the device to a computer.
If you want to switch power to ports you can use the provided kernel interface or a userland utility such as uhubctl.
