Comfospot50 full

Hardware

The schematic and PCB in this directory are the project-authored controller board design. The board is intended to interface an ESP32-C3 with the existing ComfoSpot panel. See wiring.md for the panel connections and electrical interface notes.

License scope

The project-authored schematic connectivity, PCB layout, routing, board outline, wiring diagram, and related hardware documentation are released under the CERN Open Hardware Licence Version 2 - Strongly Reciprocal, found in ../LICENSES/CERN-OHL-S-2.0.txt.

The KiCad files contain embedded component symbols and footprints selected from the JLCPCB/LCSC/EasyEDA component ecosystem and Würth's component library. Those embedded third-party elements are not relicensed by the project license. Their provenance and applicable terms are described in ../THIRD_PARTY_NOTICES.md.

The standard KiCad library elements used by the design remain subject to the KiCad library license and its design exception.

The project copyright holder is cornim. Licensing and contribution questions can be handled through GitHub for this repository.

Source location for the covered hardware design is the GitHub repository containing this file. Preserve this source location and the applicable notices when conveying the hardware design or a product made from it.

Deliberate omissions

3D model references are not included in the public PCB file. This keeps the design portable and avoids distributing model files that are not needed for schematic review, PCB editing, or fabrication. The board remains a complete 2D KiCad design and retains its footprints, pads, nets, routing, vias, zones, silkscreen, and outline.

Manufacturer datasheet PDFs are not included. Use the manufacturer or distributor source for current component documentation. The LCSC identifiers in the BOM are retained as manufacturing-selection information.

The hardware/production/comfospot50_full.zip archive contains Gerber and drill fabrication output. It is generated output and does not contain the component library or 3D model files.

Safety and no warranty

The hardware is provided "as is", without warranty of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, safety, and non-infringement. Verify voltage levels, current limits, isolation, grounding, enclosure requirements, creepage, clearance, and failure behavior before construction or use. A qualified person must review and perform any connection to an installed ventilation appliance or mains-related equipment.
