README
README.mdVynte Puck
KiCad hardware design for the Vynte room-temperature puck, part of a room-by-room HVAC comfort system.
Open the project
Open Puck.kicad_pro in KiCad. The main schematic and PCB are Puck.kicad_sch and Puck.kicad_pcb. Supporting sheets cover the temperature sensor, seven-segment display, voltage regulator, USB Type-C receptacle, and external programming interface. Custom symbols, footprints, models, and a sensor datasheet are included in Comps/. Library tables are included at the project root.
Saved fabrication files
production/ contains the existing Puck_0.5.0.zip fabrication archive, BOM/designator/placement CSV exports, IPC netlist, and stencil layers. fabrication-toolkit-options.json preserves the export settings. These files are archived exports, not a verified manufacturing release. Regenerate fabrication files from the intended design and review DRC/ERC before ordering boards.
Synchronization status
This snapshot preserves the saved local design as of October 26, 2026. Its source branch started at d32a3a6, while Gitea main had advanced by 14 commits to c4a697f. Combining the branches produces conflicts in Puck.kicad_pcb, Puck.kicad_sch, and Puck.kicad_pro. The saved design is submitted as a pull request for review; it has not been reconciled with or merged into main.
The public GitHub copy includes the development history and branch tips. Credential files have been removed throughout that history. Imported commits use Zachariah K. Sharma’s GitHub identity; original authors are credited in commit-message trailers. Rewriting this metadata changes commit IDs while preserving dates, changes, and merge structure. main retains the saved local design; gitea-main retains the upstream main branch, and the other development branches are also available. Gitea remains the development repository. Local backups, analysis caches, and per-user KiCad settings are excluded.
No open-source license has been selected.

Questions
How big is the Puck PCB?
It measures 29.7 × 72.5 mm and has 4 copper layers, 1.62 mm thick.
What parts does the Puck use?
21 parts, built around the ESP32-C6-MINI-1-N4, ET6226M, AP2112K-3.3TRG1 and B3F-4055. 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 Puck KiCad files?
From the zachariahsharma/puck repository on GitHub, at the commit this page was made from: the board is Puck.kicad_pcb and its schematic ExternalAutoprogramming.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Puck design in my own project?
Its repository states no licence, so its author keeps all rights: ask zachariahsharma before reusing the design.
