No design changes were made; the project is still empty. Execution is blocked because no ACUs are currently available.
Remaining work:
- Confirm battery type/voltage (for example, 12 V lead-acid or 3S Li-ion) and whether charging is required.
- Design a protected 12 V → 5 V buck supply for the XIAO ESP32-S3 Sense, including fuse, reverse-polarity protection, transient protection, filtering, and battery undervoltage cutoff.
- Select components, capture the schematic, and verify current/thermal margins.
After ACUs become available, use Agent mode to build and validate the circuit.
