Overview
Catch bleed is an open-source printed circuit board by BennetLeff, from the BennetLeff/temper repository on GitHub. It is a 2-layer board of 80 × 34 mm with 14 parts on 10 nets, routed with 10 tracks and 0 vias.
Its parts include 8 resistors and 4 connectors.
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.
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/) |

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 Catch bleed PCB?
It measures 80 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Catch bleed use?
14 parts. 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 Catch bleed 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/round4/catch/native/catch-bleed.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Catch bleed design in my own project?
Its repository states no licence, so its author keeps all rights: ask BennetLeff before reusing the design.
