Overview

Section is an open-source printed circuit board by BennetLeff, from the BennetLeff/temper repository on GitHub. It is a 2-layer board of 100 × 65 mm with 25 parts on 32 nets, routed with 212 tracks and 135 vias.

It is built around the SN74LVC14ADRG3, SN74LVC1G08DBVR and TPS3823-33DBVR-TP, with the RC0603FR-0710KL, B8B-XH-A(LF)(SN) and RC0603FR-071KL among its other parts. Its parts include 11 resistors, 6 capacitors, 6 ICs and 2 connectors.

Temper — 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.

Layout

Path	What 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.

Check a board

export KICAD_PYTHON=/Applications/KiCad/KiCad.app/Contents/Frameworks/Python.framework/Versions/3.9/Resources/Python.app/Contents/MacOS/Python
make -C zapote check-board BOARD=/abs/path/board.kicad_pcb PROFILE=fab-profiles/jlcpcb-2layer-2oz.json

Stackup, KiCad ERC/DRC (one finding per violation, with location and values) and fab-house DFM against a vendor profile. make -C zapote help lists the unit, layout and current checks.

Build and test

make zapote          # zapote Rust suite
make firmware-test   # firmware host tests
make bridge-python   # build zapote_bridge (uv sync)

Questions

How big is the Section PCB?

It measures 100 × 65 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Section use?

25 parts, built around the SN74LVC14ADRG3, SN74LVC1G08DBVR, TPS3823-33DBVR-TP and RC0603FR-0710KL. 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 Section KiCad files?

From the BennetLeff/temper repository on GitHub, at the commit this page was made from: the board is zapote/interlock/candidate/section.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Section design in my own project?

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