Questions
How big is the Oven2 PCB?
It measures 75 × 160 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Oven2 use?
51 parts, built around the ESP32-WROOM-32U, TMLM 05105, MAX31865ATP+ and MAX7219CWG+. 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 Oven2 KiCad files?
From the bybzmt/practise repository on GitHub, at the commit this page was made from: the board is mcu/oven2/circuit/oven2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Oven2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask bybzmt before reusing the design.
