Questions
What parts does the Load eq use?
54 parts, built around the MCP602-I/P, ICM7555N, L7805 and LM2903. 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 Load eq KiCad files?
From the dzavalishin/hardware repository on GitHub, at the commit this page was made from: the board is _Devices/load_eq/load_eq/load_eq.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Load eq design in my own project?
Its repository states no licence, so its author keeps all rights: ask dzavalishin before reusing the design.
