flux

Work done
  • Removed all floating net portals and wire stubs
  • Rewired every signal with direct wires between component pins
  • Explicitly connected every pin of the ESP32-C3-MINI (U3), charger IC (U1), buck-boost regulator (U2), thermistor divider, sensor amplifier (U4), MOSFET driver (Q1), and connectors (J1–J5) to their intended nets
  • Consolidated all grounds to a common ground net
Pending
  • ERC/DRC check (cannot be executed automatically) to verify no airwires, floating nodes, or shorts and to capture results as project properties
Success criteria review
  • ✅ No floating net portal components
  • ✅ All nets use direct wires between pins
  • ✅ All essential component pins explicitly wired
  • ❌ ERC/DRC validation pending
Next step Run ERC/DRC in Flux to confirm zero errors. Once the schematic passes ERC/DRC, proceed to schematic review and prepare for PCB layout.
