Questions
How big is the SPItoCAN PCB?
It measures 31.2 × 22.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SPItoCAN use?
30 parts, built around the TJA1051T/E/1J, MCP2515T-I/SO-HX and HSMC-C170. 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 SPItoCAN KiCad files?
From the PhoenixRacing/Sensing22_23 repository on GitHub, at the commit this page was made from: the board is SPItoCAN/SPItoCAN.kicad_pcb and its schematic RideHeightSensor/RideHeightSensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SPItoCAN design in my own project?
Its repository states no licence, so its author keeps all rights: ask PhoenixRacing before reusing the design.
