#Goal

- Complete final implementation steps on the FJ Cruiser Digital Compass project by verifying the schematic, finalizing PCB component placement, applying layout and routing rules, cleaning up DRC issues, and updating all project documentation, ensuring that the current baseline and pre-selected parts are preserved.

#Implementation plan

1. **Schematic and Baseline Verification**

1. Review the existing schematic and component connections, ensuring all key nets (e.g., VBAT_12V, VIN_PROT, +5V, +3V3, GND, I2C_SDA, etc.) remain intact.

2. Confirm that previous verification results are incorporated before proceeding with layout tasks.

2. **PCB Component Placement**

1. Place all PCB components on the 100 mm x 50 mm board per design constraints.

2. Group functional blocks:

1. Place input/power components (J1, U1) near the board edge for easy access.

2. Align U6 (seven-segment display module) for optimum dashboard viewing.

3. Isolate U5 (magnetometer) from high-noise or magnetic interfering components.

4. Arrange SW1 (calibration button) and supporting passives near associated ICs (e.g., U2, U3).

5. Position mounting holes (H1-H4) at corners with proper spacing and account for the 3 mm corner radius.

3. **Routing and Layout Rule Configuration**

1. Set and apply PCB layout rules such as trace width, clearance, and keepout/inset dimensions (0.2 mm).

2. Route remaining airwires using Auto-Route, addressing any overlapping copper issues detected earlier.

3. Run DRC/ERC checks to verify that all errors (e.g., airwires and DRC issues) have been resolved.

4. **Documentation and Project Updates**

1. Update project notes and metadata with final implementation details, component placement decisions, routing and layout rule choices, and any identified risks.

2. Archive verification status and detailed DRC cleanup actions for future reference.

#Success criteria

- The schematic remains compliant with the original design and all key nets are preserved.

- All components are correctly placed according to the grouping and positioning guidelines.

- All airwires and DRC issues are resolved with a clean DRC report.

- Project documentation is updated with final implementation notes and verification status.
