Questions
How big is the HV Probe PCB?
It measures 22 × 70 mm and has 4 copper layers, 1.61 mm thick.
What parts does the HV Probe use?
47 parts, built around the TPS5430DDA, H12VND3B, SS54 and MS110-20S. 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 HV Probe KiCad files?
From the MECSEM/electrical repository on GitHub, at the commit this page was made from: the board is HVDC/HV Probe/HV Probe.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the HV Probe design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
