Questions
How big is the Protohub PCB?
It measures 95 × 95 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Protohub use?
43 parts, built around the NCP5007SN, ATMEGA32U4, LM317S and LM7805CT. 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 Protohub KiCad files?
From the Makdaam/interface_board repository on GitHub, at the commit this page was made from: the board is protohub.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Protohub design in my own project?
Its repository states no licence, so its author keeps all rights: ask Makdaam before reusing the design.
