ESPurr hardware

Fabric/fur LED ears, headband control electronics, microphones and experimental sensing. This site brings the current hardware guides together with saved-board previews, schematics and assembly documentation.

These are development snapshots. Manufacturing packages and supplier acceptance are tracked separately in the repository. Gerbers are deliberately omitted from this site.

Start with the current plan, hardware design or build tooling. Use the Boards tab for the six source boards. Generated right ears and carriers remain owned by their validated build recipes. Firmware, app and protocol documentation lives in the ESPurr firmware site.

Ear design credit

The original ear design is by MiniStudioo, from their kitten/cat ears pattern. Some curves and shapes are reused in ESPurr's PCB design files with the creator's permission. The commercial pattern and third-party artwork are not redistributed or relicensed by this project.
