Questions

How big is the Probe PCB?

It measures 66 × 35.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Probe use?

29 parts, built around the MCP6021-E/P, MMBT3904 and MMBT3906. 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 Probe KiCad files?

From the alangarf/continuity-tester repository on GitHub, at the commit this page was made from: the board is probe/probe.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Probe design in my own project?

Its repository states no licence, so its author keeps all rights: ask alangarf before reusing the design.
