Overview

Out sensor is an open-source printed circuit board by BennetLeff, from the BennetLeff/temper repository on GitHub. It is a 2-layer board of 60 × 35 mm with 20 parts on 15 nets, routed with 65 tracks and 20 vias.

It is built around the AMC3330DWE and B6B-XH-A(LF)(SN). Its parts include 8 capacitors, 6 resistors, 2 connectors and 1 IC. It belongs with the sensors and measurement boards of this library.

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.

Questions

How big is the Out sensor PCB?

It measures 60 × 35 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Out sensor use?

20 parts, built around the AMC3330DWE and B6B-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 Out 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/out-sensor/out-sensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Out sensor design in my own project?

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