Questions
How big is the Shémas PCB?
It measures 65 × 26 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Shémas use?
43 parts, built around the TJA1051T, LM2674M-5.0, MCP3221A5-E and TCA9517D. 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 Shémas KiCad files?
From the CarlDominicA/Projet_Module_CAN repository on GitHub, at the commit this page was made from: the board is Session_H24/Matériel/PCB/Shémas.kicad_pcb and its schematic Session_H24/Matériel/PCB/Shémas.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shémas design in my own project?
Its repository states no licence, so its author keeps all rights: ask CarlDominicA before reusing the design.
