README
README.mdTemper — ESP32-S3 Induction Cooker
Temper is a consumer induction cooker: a 120 V full-bridge power stage, isolated gate drive, sensing and protection units, and ESP32-S3 firmware with an 8-state transition-table machine and hardware-latched protection.
Implementation and qualification status lives with the evidence, not here: see zapote/CHECKS.md and each unit's acceptance record. Nothing has been qualified on hardware.

Questions
How big is the Cooker PCB?
It measures 164 × 234 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Cooker use?
171 parts, built around the IKW40N120H3, ESP32-S3-WROOM-1-N8R8, IRM-10-15 and MAX31865AAP+. 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 Cooker KiCad files?
From the BennetLeff/temper repository on GitHub, at the commit this page was made from: the board is zapote/rtd/candidate/cooker.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cooker design in my own project?
Its repository states no licence, so its author keeps all rights: ask BennetLeff before reusing the design.
