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 Iline sensor PCB?
It measures 45 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Iline sensor use?
8 parts, built around the AC1020 and B2B-XH-A(LF)(SN). 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 Iline sensor KiCad files?
From the BennetLeff/temper repository on GitHub, at the commit this page was made from: the board is zapote/power-stage-120v/prototype-closure/round5/boards/native/iline-sensor/iline-sensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Iline sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask BennetLeff before reusing the design.
