Questions
How big is the CanBus PCB?
It measures 87 × 55.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CanBus use?
61 parts, built around the TCAN332D and AP2112K-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 CanBus KiCad files?
From the BrianEstime1/CANBUS-NODE-PCB repository on GitHub, at the commit this page was made from: the board is CanBus.kicad_pcb and its schematic CanBus.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CanBus design in my own project?
Its repository states no licence, so its author keeps all rights: ask BrianEstime1 before reusing the design.
