Questions
How big is the Logic probe PCB?
It measures 9.7 × 30.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Logic probe use?
22 parts, built around the NE555. 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 Logic probe KiCad files?
From the CRImier/pcb_logic_probe repository on GitHub, at the commit this page was made from: the board is logic_probe.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Logic probe design in my own project?
Its repository states no licence, so its author keeps all rights: ask CRImier before reusing the design.
