espurr firmware

Motion-reactive RGB cat ears that run on their own. Your phone adds detailed controls, calibration and updates; it doesn't render frames for the headset.

Get started

1. Choose your hardware and check the wiring.
2. Install firmware over USB.
3. Pair your phone, then set up colours and motion.

The USB installer stays separate from these guides. Hardware and board documentation lives in the hardware project. The phone app download links on the installer are placeholders for now.

Development and evidence

Build from source, run tests, or read about CI and releases and maintaining this site. Native app development is covered in the Apple and Android guides, with shared decisions in mobile parity.

These pages describe the current source tree. Firmware versions, application protocol, catalogue schema and settings storage versions are separate identities. The installer release selector chooses binaries; it does not change the docs.

Current status lists remaining integration and physical qualification work. History contains dated evidence and superseded plans. Store submission and privacy drafts remain repository-only planning documents. The copy guide records the approved name and marketing copy. The store-listing draft contains copy, editable artwork and captured screenshots; affected images need recapturing for release.
