Questions
How big is the CAN PCB?
It measures 26 × 30 mm and has 4 copper layers, 0.8 mm thick.
What parts does the CAN use?
48 parts, built around the ESP32-C3, SN65HVD230D, AP2112K-3.3 and FODM217D. 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 CAN KiCad files?
From the hoellwerth/Expansioncards repository on GitHub, at the commit this page was made from: the board is CAN/Electrical/CAN.kicad_pcb and its schematic 2-usb-c/Electrical/2-usb-c.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CAN design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
