Questions
How big is the CANNode PCB?
It measures 66.5 × 57 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CANNode use?
51 parts, built around the MAX3485ED, SN65HVD230D and PCA9306D. 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 CANNode KiCad files?
From the wiebel/CANNode repository on GitHub, at the commit this page was made from: the board is Hardware/kicad/CANNode.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CANNode design in my own project?
Its repository states no licence, so its author keeps all rights: ask wiebel before reusing the design.
