Questions
How big is the Physical electronics oven PCB?
It measures 113 × 78.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Physical electronics oven use?
35 parts, built around the MCP9600-E/MX and AO3400A. 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 Physical electronics oven KiCad files?
From the andreicito2/Physical-electronics-oven repository on GitHub, at the commit this page was made from: the board is Physical Electronics Oven/Physical Electronics Oven.kicad_pcb and its schematic Physical Electronics Oven/Physical Electronics Oven.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Physical electronics oven design in my own project?
Its repository states no licence, so its author keeps all rights: ask andreicito2 before reusing the design.
