Questions
What parts does the OpenPowerDistribution use?
537 parts, built around the CH340C, ESP32-WROOM-32, LAN8720AI-CP-TR-ABC and LM324. 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 OpenPowerDistribution KiCad files?
From the ulikoehler/OpenPowerDistributor repository on GitHub, at the commit this page was made from: the board is OpenPowerDistributor/OpenPowerDistribution.kicad_pcb and its schematic OpenPowerDistributor/24V boost.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenPowerDistribution design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
