#Goal

- Complete the remaining schematic connections and PCB routing of the ESP32 PBR Controller so that the design becomes prototype-ready.

#Implementation plan

1. Complete Schematic Connectivity

1. Review the power/output sections and connect any remaining components, ensuring proper connections between the power supply, regulators, sensors, and actuators.

2. Verify routing connections to test-points, headers, and connectors for complete signal continuity.

2. Organize PCB Zones

1. Divide the board into distinct areas for power, logic (ESP32 and control circuitry), analog sensing, and high-current outputs.

2. Clearly label each zone and review net assignments to avoid cross-zone interference.

3. PCB Routing

1. Apply layout guidelines specific to each zone, ensuring appropriate trace widths and clearance for power, signal, and high-current paths.

2. Use auto-routing to connect nets within each zone while manually reviewing critical paths, especially in power and high-current outputs.

3. Validate connectivity using design rule checks to ensure no unrouted or conflicting connections remain.

4. Final Review

1. Cross-check the schematic against the PCB layout ensuring all components are correctly routed and connected.

2. Update project documentation with the final schematic and board routing changes.

#Success criteria

- All schematic connectivity issues, especially in the power and output sections, are resolved.

- PCB is fully routed with axes segmented into power, logic, analog, and high-current zones.

- Design rule checks confirm a complete connection with no errors, making the design ready for prototype review.
