Questions
How big is the Schema electrique PCB?
It measures 42 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Schema electrique use?
30 parts, built around the ATMEGA16U4-MU and LMH6611MK. 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 Schema electrique KiCad files?
From the LeaGuyon/M1 repository on GitHub, at the commit this page was made from: the board is Conception circuit/ATCE/schema_electrique(1)/schema_electrique/schema_electrique.kicad_pcb and its schematic Conception circuit/ATCE/archive circuit/kicad/atmega_kicad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Schema electrique design in my own project?
Its repository states no licence, so its author keeps all rights: ask LeaGuyon before reusing the design.
