Aurora Hearing Device Design
Worked for 29 sec
Blocked: your account is currently out of ACUs, so I can’t mutate the board/layout further in this run.
Accomplished this session:
- Started the 12 mm product-like redesign workflow.
- Loaded the required layout/component procedures for the crescent board, compact part replacement, and placement constraints.
- Confirmed the next execution plan: 12 mm max-width smooth crescent, 4-layer stackup, compact USB-C replacement, high-SPL mic replacement, removal/shrinking of bulky hook-side parts, and dense two-sided placement.
Remaining:
- Apply the new 12 mm crescent board outline and 4-layer stackup.
- Replace/flag oversized parts: current USB-C, ICS-40730 mics, large flash, tactile switch, and bulky connectors.
- Re-place the hook PCB components into the slim crescent form factor.
- Run layout fit/congestion checks and update the project documentation.
Thought for 5 sec
Estimate: ~25–45 ACUs to finish a credible 12 mm hook redesign pass.
Breakdown:
- Apply 12 mm crescent outline + 4-layer stackup: 2–5 ACUs
- Research/replace compact USB-C + high-SPL mics + smaller flash/switch/connectors: 6–12 ACUs
- Re-place dense two-sided hook layout: 8–15 ACUs
- Fit/congestion/layout verification: 4–8 ACUs
- Update project docs and next-step notes: 2–5 ACUs
If we also route the board afterward, budget another 40–90 ACUs, because fine-pitch nRF5340/CS47L63, RF, USB, and dense wearable placement will likely need multiple iterations.
Proceed after ACUs
Prioritize fit check
Research compact parts
Update migration plan
Review power impact
