Detection and Locating Device Design

Work done
  • Reviewed the existing schematic, BOM, layout, and DRC/ERC state for the passive receive-only RF detector/locator.
  • Confirmed the board is kept at 100 x 160 mm with a 4-layer stackup and applied baseline layout rules for manufacturable routing density.
  • Audited the main subsystems: IC1, U1, U2, U3, U5, U6, U7, J1, J2, J3, D1, and DISP1.
  • Added project metadata documenting passive-only compliance and zoning intent.
  • Tried to clear the footprint issue on U2 by reinforcing its package metadata, but the footprint check still reports it as unresolved.
Success criteria review
  • ❌ All schematic airwires are not resolved. Review still reports 173 airwires in the layout.
  • ❌ All footprints are not valid. U2 still reports a missing footprint.
  • ❌ The PCB is configured, but I could not complete component placement and feasible routing from the tools available in this run.
  • ✅ Passive-only compliance is documented and preserved in the design intent and project metadata.
Next steps The remaining work requires a PCB placement/routing action capability that is not available in this run, plus a direct footprint reassignment path for U2. If those become available, the next actions are: assign the correct U2 footprint, place all components by RF/power/digital/storage zones, run Auto-Layout or manual routing, then re-run DRC until airwires are cleared.

Keep board constraints
Fix footprint mismatches
