Questions
How big is the Steering wheel unit PCB?
It measures 90 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Steering wheel unit use?
127 parts, built around the SN65HVD232D, TPS62933DRL, LM76202QPWPRQ1 and USBLC6-2P6. 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 Steering wheel unit KiCad files?
From the HydrogreenPollub/pcb-steering-wheel-unit repository on GitHub, at the commit this page was made from: the board is steering_wheel_unit/steering_wheel_unit.kicad_pcb and its schematic steering_wheel_unit/io.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Steering wheel unit design in my own project?
Its repository states no licence, so its author keeps all rights: ask HydrogreenPollub before reusing the design.
