Questions
How big is the ECAN PCB?
It measures 39.6 × 49.5 mm and has 4 copper layers, 1.59 mm thick.
What parts does the ECAN use?
47 parts, built around the SN65HVD232D. 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 ECAN KiCad files?
From the aesirkth/external-can repository on GitHub, at the commit this page was made from: the board is external_can_PCB/ECAN.kicad_pcb and its schematic external_can_PCB/ECAN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ECAN design in my own project?
Its repository states no licence, so its author keeps all rights: ask aesirkth before reusing the design.
