Matchboxscope/Omniscope-USB-HubA simple 4-port USB2 hub based on the SL2.1A design.
USB 2.0 Hub is an open-source printed circuit board by Matchboxscope, from the Matchboxscope/Omniscope-USB-Hub repository on GitHub. It is a 2-layer board of 83.7 × 22.5 mm with 32 parts on 37 nets, routed with 351 tracks and 63 vias.
It is built around the SL2.1A and RB521S30T1G-DW. Its parts include 11 capacitors, 11 resistors, 5 connectors, 2 diodes and 1 IC.

A simple 4-port USB2 hub based on the SL2.1A design. This board is designed in KiCAD v7! It is based off an earlier 2021 design with USB-A outputs.
This revises the board to provide USB2 Type-C outputs. By default, the schematic provides circuitry for default USB power (500mA) but resistor values can be changed to provide higher output current if available through external power.
These boards have been tested and built with OSHPark After Dark service.

32 parts, built around the SL2.1A and RB521S30T1G-DW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Matchboxscope/Omniscope-USB-Hub repository on GitHub, at the commit this page was made from: the board is USB 2.0 Hub.kicad_pcb and its schematic USB 2.0 Hub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Matchboxscope before reusing the design.
