Questions
How big is the First PcB PCB?
It measures 38 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the First PcB use?
10 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 First PcB KiCad files?
From the Mohammed-Assem/SImple-PCB repository on GitHub, at the commit this page was made from: the board is first_PcB/first_PcB.kicad_pcb and its schematic first_PcB/first_PcB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the First PcB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mohammed-Assem before reusing the design.
