JUST PlUG IT INTO YOUR COMPUTER VIA THE INPUT
Why did I built it
I built this project because I wanted learn more about usb hubs and their working , WHile this hub also helps me to work with my RPI 2 zero , which dosent have many usb ports and hence allowing me to connect multiple peripeheral devices to it

Questions
How big is the Erbium PCB?
It measures 48 × 57 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Erbium use?
27 parts. 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.
Where can I download the Erbium KiCad files?
From the Enderman8843/Erbium repository on GitHub, at the commit this page was made from: the board is PCB/Erbium.kicad_pcb and its schematic PCB/Erbium.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Erbium design in my own project?
Its repository states no licence, so its author keeps all rights: ask Enderman8843 before reusing the design.
