Questions
How big is the Routing settings PCB?
It measures 56 × 56 mm and has 4 copper layers, 2.63 mm thick.
What parts does the Routing settings use?
125 parts, built around the STM32L433CCU6, AP63205WU, NCP360SN and TB67S249FTG,EL. 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 Routing settings KiCad files?
From the rx178nwj/StepperMotorDriver-Node repository on GitHub, at the commit this page was made from: the board is schematic_NEMA23/review/jlcpcb-4layer/settings-import/routing-settings.kicad_pcb and its schematic schematic_NEMA17/schematic_NEMA17.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Routing settings design in my own project?
Its repository states no licence, so its author keeps all rights: ask rx178nwj before reusing the design.
