Questions
How big is the IO Daughter Board PCB?
It measures 100 × 72.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IO Daughter Board use?
18 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 IO Daughter Board KiCad files?
From the OSHE-Github/Smart-BREAD repository on GitHub, at the commit this page was made from: the board is Loaf/PCB/DaughterBoard/IO_Daughter_Board.kicad_pcb and its schematic Loaf/PCB/5V4A VRM Module/VRM Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IO Daughter Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask OSHE-Github before reusing the design.
