Questions
How big is the USBtoCANFD PCB?
It measures 17 × 35.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USBtoCANFD use?
32 parts, built around the MCP2562FD-E/P, LP5907UVX-3.3, AR0521P1 and K3-1293S-E2. 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 USBtoCANFD KiCad files?
From the rbtsco/USB2CAN repository on GitHub, at the commit this page was made from: the board is Board/USBtoCANFD.kicad_pcb and its schematic Board/USBtoCANFD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USBtoCANFD design in my own project?
Its repository states no licence, so its author keeps all rights: ask rbtsco before reusing the design.
