Questions
How big is the SteeringHardware PCB?
It measures 87 × 55.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SteeringHardware use?
62 parts, built around the TPS5430DDA, AMS1117-5.0, TPS2113PW and AO3400A. 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 SteeringHardware KiCad files?
From the John-Carr/SteeringHardware repository on GitHub, at the commit this page was made from: the board is SteeringHardware.kicad_pcb and its schematic MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SteeringHardware 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).
