Questions
How big is the HV Controller PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.61 mm thick.
What parts does the HV Controller use?
283 parts, built around the RP2350B, 74HC245D, SN74LVC827APWR and SN65LVDS1DBV. 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 Controller KiCad files?
From the MECSEM/electrical repository on GitHub, at the commit this page was made from: the board is HVDC/HV Controller/HV Controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the HV Controller 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).
