Questions
How big is the Stepperdriver front panel PCB?
It measures 133 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stepperdriver front panel use?
23 parts, built around the XZMDKCBDDG45S-9, 37204-62A3-004PL and 37212-62A3-003PL. 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 Stepperdriver front panel KiCad files?
From the harp-tech/device.stepperdriver repository on GitHub, at the commit this page was made from: the board is Hardware/PCB/stepper driver front panel/stepperdriver front panel.kicad_pcb and its schematic Hardware/PCB/stepper driver front panel/stepperdriver front panel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stepperdriver front panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask harp-tech before reusing the design.
