Questions
How big is the Power Supply ZensatV3 PCB?
It measures 86 × 86 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Power Supply ZensatV3 use?
132 parts, built around the SN65HVD233D, LMR33630ADDA, AMS1117-3.3 and LM234DT. 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 Power Supply ZensatV3 KiCad files?
From the zenitheesc/ZenSat-V3-EPS repository on GitHub, at the commit this page was made from: the board is Main Board/Kicad/Power Supply ZensatV3.kicad_pcb and its schematic Main Board/Kicad/Power Supply ZensatV3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power Supply ZensatV3 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
