Left ear flex

The manually maintained left ear is the source for ESPurr v2's flex design: 69 RGB LEDs, a rear FFC connector and an AW96105 sensor connected to three rear electrodes. Through-fur sensing remains experimental. Routing, connector support, manufacturing details and physical validation are still in progress. The downloadable PCB is a development snapshot.

The front/back illustrations use an off-white coverlay and ENIG palette, with covered copper hidden. The angled view uses the saved 0.12mm nominal CAD stack and available component models; native DNP component bodies are hidden. These illustrate the design rather than a measured production finish. Actual white coverlay may make the finished flex thicker than the nominal CAD model.

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.
