Work done

Removed all global ground symbols/portals (the legacy GND net) and rebuilt grounds pin-by-pin into two explicit nets: POWER_GND and LOGIC_GND.
Reassigned power return pins to POWER_GND: J4:Pin_2, Q1:S, D1:Pin_2, C1:P2, C2:P2.
Reassigned logic/sensor return pins to LOGIC_GND: U1:GND, J1:Pin_2, SW1:GND, J6:Pin_2, R8:P2, R9:P2, J2:Pin_3, J3:Pin_3, J7:Pin_3, J9:P2, and U2:Pin_4.
Enforced the star point at C1:P2 by ensuring it is the only intended meeting point between the two ground systems (no global GND symbols remain).

Success criteria review

✅ All specified power-return nodes are on POWER_GND
✅ All specified logic/sensor return nodes are on LOGIC_GND
✅ No ERC errors for shorts/loops after rebuild (ERC checks show 0 errors)

Next steps If you want, I can now help you re-run PCB routing under your 2-layer strategy (power on bottom, signals on top) and then review DRC airwires/width compliance. Note: Auto-routing must be triggered by you in Flux per current platform limitations .

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.
