Questions
How big is the Car PCB?
It measures 88 × 97.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Car use?
92 parts, built around the CH340C, HC-05, DRV8870DDA and TPS5430DDA. 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 Car KiCad files?
From the XAUT-WisdomLab/stm32_car_drive repository on GitHub, at the commit this page was made from: the board is hardware/pcb/stm32_car_drive_v2.0.0/car.kicad_pcb and its schematic hardware/pcb/stm32_car_drive_v1.0.0/bb68942b.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Car design in my own project?
Its repository states no licence, so its author keeps all rights: ask XAUT-WisdomLab before reusing the design.
