Questions
How big is the DiffProbe PCB?
It measures 42.9 × 36 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DiffProbe use?
37 parts, built around the LT1761-BYP. 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 DiffProbe KiCad files?
From the land-boards/lb-boards repository on GitHub, at the commit this page was made from: the board is Test Equipment Cards/DiffProbe/DiffProbe.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DiffProbe design in my own project?
Its repository states no licence, so its author keeps all rights: ask land-boards before reusing the design.
