Questions
How big is the StepperCAN PCB?
It measures 42 × 42 mm and has 4 copper layers, 1.62 mm thick.
What parts does the StepperCAN use?
23 parts, built around the STM32G0B1KBU6N, 50ZLH100MEFC8X11.5 and NUP2105LT1G. 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 StepperCAN KiCad files?
From the zachariahsharma/FDM3DP repository on GitHub, at the commit this page was made from: the board is StepperCAN/StepperCAN.kicad_pcb and its schematic FDM3DP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the StepperCAN design in my own project?
Its repository states no licence, so its author keeps all rights: ask zachariahsharma before reusing the design.
