Questions
How big is the Peson numerique PCB?
It measures 45.5 × 144.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Peson numerique use?
21 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 Peson numerique KiCad files?
From the Gphoebus/peson repository on GitHub, at the commit this page was made from: the board is kicad_files/peson_numerique.kicad_pcb and its schematic kicad_files/peson_numerique.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Peson numerique design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gphoebus before reusing the design.
