Telephone Audio Guestbook Design

Good news: D1 is on the PCB and has a footprint (0402 TVS). The “Missing Footprints” DRC is clear. You’re likely just not seeing it on canvas.
What Flux docs say about finding it “Navigation
  • Click on any category to expand or collapse it
  • Use the search field at the top to find specific objects by name
  • Right-click on the tree background for additional view options
Selection
  • Click on any object in the tree to select it in the PCB editor
  • Hold Shift to select multiple consecutive objects
  • Hold Ctrl (or Cmd on Mac) to select multiple non-consecutive objects
  • Right-click on an object for a context menu of actions
Visibility Control
  • Click the eye icon next to any object to toggle its visibility
  • Use the visibility controls at the top of the tree to show/hide entire categories
  • Right-click and select ‘Hide Others’ to focus on specific elements” Source
Do this
  • Open the Objects list and type “D1” in the search field; click it to select. The footprint will highlight on canvas. If it’s still not visible, use the eye icon to ensure it isn’t hidden.
Current DRC summary
  • Airwires: EN, IO0, RXD0, TXD0 between U1 and test pads TP1/TP2/TP3/TP4. No “Missing Footprints” errors.
When you’ve located D1, tell me and I’ll guide you to place it close to J2 and clear the airwires next.
