Questions
How big is the High voltage servo drive 3ch PCB?
It measures 109 × 231.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the High voltage servo drive 3ch use?
487 parts, built around the STM32G473QET6, SP491EEN-L/TR, 74LVC1G126Z and F0505S-1W. 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 High voltage servo drive 3ch KiCad files?
From the ExcessiveOverkill/hvsd-3ch repository on GitHub, at the commit this page was made from: the board is KiCad/high voltage servo drive 3ch/high voltage servo drive 3ch.kicad_pcb and its schematic KiCad/high voltage servo drive 3ch/STO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the High voltage servo drive 3ch design in my own project?
Its repository states no licence, so its author keeps all rights: ask ExcessiveOverkill before reusing the design.
