Questions
How big is the ArdCurvTracer PCB?
It measures 92.1 × 88.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ArdCurvTracer use?
64 parts, built around the LM358, MCP4802-E/P, HT7533 and HT7550. 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 ArdCurvTracer KiCad files?
From the jonsag/ardCurveTracer repository on GitHub, at the commit this page was made from: the board is KiCad/ardCurvTracer/ardCurvTracer.kicad_pcb and its schematic KiCad/ardCurvTracer/ardCurvTracer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ArdCurvTracer design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonsag before reusing the design.
