Questions
How big is the Bootcamp elec PCB?
It measures 23.7 × 31.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bootcamp elec use?
18 parts, built around the ATMEGA328P-AU. 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 Bootcamp elec KiCad files?
From the Molasz/42outer-bootcamp-elec repository on GitHub, at the commit this page was made from: the board is bootcamp-elec.kicad_pcb and its schematic bootcamp-elec.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bootcamp elec design in my own project?
Its repository states no licence, so its author keeps all rights: ask Molasz before reusing the design.
