Questions
How big is the STM32GenericBoard PCB?
It measures 50.8 × 50.8 mm and has 6 copper layers, 1.6 mm thick.
What parts does the STM32GenericBoard use?
62 parts, built around the SN65HVD234D, AMS1117-3.3, ICM-45686 and US2AA. 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 STM32GenericBoard KiCad files?
From the pitounet75/RobotRL repository on GitHub, at the commit this page was made from: the board is Board/STM32GenericBoard/STM32GenericBoard.kicad_pcb and its schematic Board/STM32GenericBoard/STM32GenericBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32GenericBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask pitounet75 before reusing the design.
