Questions
How big is the FETProbe V2 PCB?
It measures 23 × 15 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FETProbe V2 use?
21 parts, built around the SPX3819M5-L/TR, RF15N2R2B500CT, CONMHF1-SMD-G-T and GRM3195C1H104GA05D. 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 FETProbe V2 KiCad files?
From the makerprobe/FETProbe_V2 repository on GitHub, at the commit this page was made from: the board is FETProbe_v2.kicad_pcb and its schematic FETProbe_v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FETProbe V2 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
