Questions
How big is the HVDCDC PCB?
It measures 40 × 20 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HVDCDC use?
36 parts, built around the IR2181PBF, AMS1117-3.3 and BSC105N10LSF G. 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 HVDCDC KiCad files?
From the davidmolony/HVDCDC repository on GitHub, at the commit this page was made from: the board is HVDCDC/HVDCDC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the HVDCDC design in my own project?
Its repository states no licence, so its author keeps all rights: ask davidmolony before reusing the design.
