Questions
How big is the Stepper driver pcb PCB?
It measures 42 × 42 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stepper driver pcb use?
93 parts, built around the STM32G431CBT6, AS5047P-ATSM, TPSM84209RKHR and CDBA140SL-HF. 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 Stepper driver pcb KiCad files?
From the robotastic-youtube/Projekte repository on GitHub, at the commit this page was made from: the board is 6R Robot/Electronics/stepper_driver_pcb/stepper_driver_pcb.kicad_pcb and its schematic 6R Robot/Electronics/stepper_driver_pcb/stepper_driver_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stepper driver pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask robotastic-youtube before reusing the design.
