Use hierarchical sheets to simplify functionalities. Instead of cluttering a root sheet, keep it as a high-level block diagram and place detailed connectors on sub-sheets. Standardized Representation: Follow international standards like IEC 61082-1

Houses the primary switching regulator IC, which steps down raw input voltage to stable logic-level outputs (3.3V or 5V). Signal Processing & Control Node

: Inspect the feedback resistor divider network. Even a 1% deviation in resistor value can cause the S12022 to output incorrect voltage or enter a thermal shutdown loop. Enable / Shutdown (EN / SHDN)

The lock snapped. Heavy boots thudded against the concrete floor.
