Questions
How big is the Wss PCB?
It measures 55 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wss use?
21 parts, built around the 74HC14. 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 Wss KiCad files?
From the Full-Blue-Racing/FBR-Wheel-Speed-Sensor repository on GitHub, at the commit this page was made from: the board is wss.kicad_pcb and its schematic car_connection.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wss design in my own project?
Its repository states no licence, so its author keeps all rights: ask Full-Blue-Racing before reusing the design.
