Questions
How big is the Canbus tire temp sensor PCB?
It measures 40 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Canbus tire temp sensor use?
42 parts, built around the TCAN3403DRQ1, MLX90641ESF-BCA-000-SP, TLE42744DV33ATMA1 and ECS-160-10-36Q-AES-TR. 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 Canbus tire temp sensor KiCad files?
From the bglen/canbus_tire_temp_sensor repository on GitHub, at the commit this page was made from: the board is hardware/PCB/canbus_tire_temp_sensor.kicad_pcb and its schematic hardware/PCB/canbus_tire_temp_sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Canbus tire temp sensor 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).
