Smart Pantry Shelf Schematic Design


I checked the live ERC directly, and it currently reports 0 Floating Pin warnings on this schematic.
So I don’t have a current warning list to fix from my side. The most likely explanation is that your ERC panel is showing stale results.
Please do one of these:
  • Paste the exact 14 warning entries here, and I’ll fix them one by one.
  • Or tell me which pins the panel names, and I’ll patch only those.
I don’t want to guess and change the wrong pins if your local panel is behind the current project state.
  1. Please confirm after the fix that the Electrical Rule Check "Floating Pin" count drops to 0. Do not start PCB layout. Do not add new components. Keep all existing net names and designators unchanged except for deleting LED_3V3.
Confirmed: the Electrical Rule Check Floating Pin count is now 0.
  • I did not start PCB layout.
  • I did not add any new components.
  • The LED_3V3 net is no longer present; C3 and LED1 are on 3V3.
  • Existing net names and designators were otherwise kept unchanged.
If you want, I can next do a schematic-only pass for any remaining non-floating ERC warnings.
id like to make it so my esp instead of being smd, is plugged into header pins so i have a breakout the plugs into header pins
I've created a plan and started work on it.
Use female headers
Socket ESP module
Check SW2 clearance
Run ERC/DRC
