Questions
How big is the Pcb1 PCB?
It measures 46.3 × 36.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcb1 use?
33 parts, built around the AMS1117-3.3. 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 Pcb1 KiCad files?
From the Eben113/Pcb-project-1 repository on GitHub, at the commit this page was made from: the board is Pcb1.kicad_pcb and its schematic Pcb1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Eben113 before reusing the design.
