Overview
Sh03-controller is an open-source printed circuit board by penmoid, from the penmoid/sh03-pcb repository on GitHub, published under the CERN-OHL-P-2.0 licence. It is a 2-layer board of 100 × 56 mm with 18 parts on 41 nets, routed with 290 tracks and 64 vias.
It is built around the ESP32-S3-DEVKITC-1-N8. Its parts include 4 resistors, 3 capacitors, 3 connectors and 1 IC. It belongs with the ESP32 boards of this library.
Main components
1README
README.mdSH03 controller
SH03 controller is an ESP32-S3-DevKitC-1 carrier board for the Sovol SH03 filament dryer. The board is a two-layer, 100 × 56 mm design. It carries nine back-side SMD references: J1, J2, R1-R4, and C1-C3. J3 and the DevKitC-1 headers are through-hole parts fitted by the builder.
This repository contains the KiCad source, custom footprints, schematic exports, fabrication files, renders, validation reports, and regeneration scripts. The current design is Rev-A.
Validation status
The repository documents CAD, DRC/ERC, routing, placement, and fabrication checks. The project author has personally validated correct operation of the assembled Rev-A board in the dryer. Perform the checks in docs/bring-up.md before connecting a board to a dryer.
No firmware is included. The GPIO assignments are documented in docs/gpio-remap.md.
Fabrication
The upload package is in fab/. Read fab/README.md before ordering. The package contains Gerbers, a BOM, a CPL, and a STEP export.
The BOM and sourcing notes are in docs/bom.md. Connector mate compatibility and all order-time sourcing information require confirmation before an order.
Images
The angled render does not include a resolved J2 3D model.
Toolchain
The source was generated and checked with KiCad 10.0.5. The scripts use the
standalone pcbnew Python module. The fab guide includes the kicad-cli
commands for Gerbers, drills, CPL, SVG, 3D renders, and schematic PDF export.
The board generation pipeline is documented in docs/layout-plan.md:
scripts/place_footprints.py
scripts/route_board.py
scripts/add_ground_pour.py
scripts/add_fiducials.pyRun scripts/check_placement.py, scripts/report_pads.py, and
scripts/check_determinism.py after regeneration.
Licensing
Hardware and documentation are covered by CERN-OHL-P-2.0. Scripts are covered by MIT. See NOTICE.md for third-party and KiCad-derived footprint exceptions.

Questions
How big is the Sh03-controller PCB?
It measures 100 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sh03-controller use?
18 parts, built around the ESP32-S3-DEVKITC-1-N8. 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 Sh03-controller KiCad files?
From the penmoid/sh03-pcb repository on GitHub, at the commit this page was made from: the board is sh03-controller.kicad_pcb and its schematic sh03-controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sh03-controller design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
