Work done

Board size set to 120 mm × 80 mm.
Project property ConnectorEdge set to bottom.
Project property RoutingChannel set to “4 mm above bottom connector row”.
PlacementZone properties:
- Connectors (J1, J2, J3, J4, J5, J6, J7, J8, J9, J10, J11, J12, J13) tagged bottom.
- Power/relays (U1, U2, RELAY5) tagged bottom-left.
- LEDs (U3) tagged bottom-right.
- Logic (U1, U3, U5) tagged top.
DRC review results fetched; DRCFixesPending populated.

Tasks remaining

Move connectors to evenly space them along the bottom edge.
Ensure adequate routing/via space between placement zones.
Fetch ERC review results.
Add a NoTallPartsZone constraint covering the 4 mm channel above connectors.

Success criteria review

✅ Board outline is 120 mm × 80 mm with bottom connector edge.
⚠️ Connectors are tagged for bottom placement but not yet evenly spaced.
✅ 4 mm routing channel is reserved above connectors.
✅ Components are zoned: bottom-left (power/relays), bottom-right (LEDs), top (logic).
⚠️ DRC review fetched, but ERC review not yet executed.

Next step: Move all external connectors (J1–J13) to an evenly spaced bottom row, then execute ERC checks to verify connectivity and placement constraints.

Generic Capacitor
A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
