Overview

Supervisor is an open-source printed circuit board by BennetLeff, from the BennetLeff/temper repository on GitHub. It is a 4-layer board of 275 × 240 mm with 440 parts on 280 nets, routed with 5,945 tracks and 641 vias.

It is built around the STM32G071RBT6, SN74AHCT125PWRE4 and TLV9061IDBVR-MS, with the ADS131M08IPBSR, SN74LVC1G08DBVR and TLV3201AIDBVR(LX) among its other parts. Its parts include 150 resistors, 147 capacitors, 108 ICs, 24 connectors and 4 transistors. It belongs with the STM32 boards of this library.

Temper — ESP32-S3 Induction Cooker

zapote Firmware Tests License

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.

Layout

PathWhat it is
zapote/Board validation workspace: Rust ERC/DRC/DFM, the five standalone units (RTD, current-sense, thermal-sense, interlock, gate-drive), the 120 V power stage, native KiCad adapters and fab-house profiles
firmware/ESP32-S3 firmware, host tests, code generators and state-machine/invariant gates (firmware/tools/)
components/, datasheets/Part documentation and datasheets
docs/, skills/, output/Plans, evidence and history; product/PCB/mechanical review skills; mechanical and prototype outputs

The legacy placer/router, the old production board (pcb/, elec/), datasets, dashboards and their CI were removed on 2026-10-08. Everything is recoverable from tag archive/temper-legacy-2026-10-08.

Questions

How big is the Supervisor PCB?

It measures 275 × 240 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Supervisor use?

440 parts, built around the STM32G071RBT6, SN74AHCT125PWRE4, TLV9061IDBVR-MS and ADS131M08IPBSR. 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 Supervisor 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/central/native/supervisor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Supervisor design in my own project?

Its repository states no licence, so its author keeps all rights: ask BennetLeff before reusing the design.
