From the project
AURA: open wearable note-taking device development — PCB, printable case, firmware, Next.js/Convex notes, interactive 3D site and launch film.
This directory does not contain a fabrication-ready PCB release. Do not order the placement export or standalone session.
See ../../docs/hardware.md for charging, cell, RF, acoustic, mechanical and software qualification limits. The earlier connector SES import was cancelled without an explanation. No alternative import was performed to bypass it. A standalone routing session is not an independently checked routed KiCad board.
