Questions
How big is the Multiprobe PCB?
It measures 50 × 63 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Multiprobe use?
26 parts. 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 Multiprobe KiCad files?
From the PietPtr/picotide repository on GitHub, at the commit this page was made from: the board is pcbs/multiprobe/multiprobe.kicad_pcb and its schematic pcbs/minsync/RP2040_minimal_r2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Multiprobe design in my own project?
Its repository states no licence, so its author keeps all rights: ask PietPtr before reusing the design.
