Questions
How big is the Oven PCB?
It measures 75 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Oven use?
47 parts, built around the MAX31865ATP+, MAX7219CWG+ and AMS1117-3.3. 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 Oven KiCad files?
From the bybzmt/practise repository on GitHub, at the commit this page was made from: the board is mcu/oven/circuit/test.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Oven design in my own project?
Its repository states no licence, so its author keeps all rights: ask bybzmt before reusing the design.
