Questions
How big is the Diff probe PCB?
It measures 39 × 12 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Diff probe use?
9 parts, built around the AD8130AR. 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 Diff probe KiCad files?
From the andrastantos/the_d_machine repository on GitHub, at the commit this page was made from: the board is modules/diff_probe/diff_probe.kicad_pcb and its schematic circuit_sims/and_or_not/and_or_not.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Diff probe design in my own project?
Its repository states no licence, so its author keeps all rights: ask andrastantos before reusing the design.
