Questions
How big is the Hv sense PCB?
It measures 99.1 × 74.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hv sense use?
71 parts, built around the TLV274D, TL431ACDT and BAT54W. 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 sense KiCad files?
From the sufst/tsal repository on GitHub, at the commit this page was made from: the board is hardware/hv_sense/hv_sense.kicad_pcb and its schematic hardware/hv_sense/hv_sense.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hv sense design in my own project?
Its repository states no licence, so its author keeps all rights: ask sufst before reusing the design.
