Work done
  • Ho sostituito SW1 e SW2 con SW1 e SW2, che sono i 2-pin piu' semplici disponibili in libreria senza morsetto a vite.
  • Ho ricablato SW1 su BAT e BAT_SW, e SW2 su BTN_PD2 e GND.
  • Ho verificato schematico, layout, BOM ed ERC/DRC dopo la sostituzione.
Success criteria review
  • ✅ I due TB003 originali sono stati rimossi e sostituiti nello schematico e nel layout
  • ✅ Il collegamento funzione batteria e' stato preservato su SW1
  • ✅ Il collegamento del pulsante esterno e' stato preservato su SW2
  • ❌ Non posso dichiarare il lavoro completamente chiuso rispetto al piano, perche' il progetto ha ancora violazioni ERC/DRC preesistenti e il net BAT_SW resta collegato solo a SW1, mentre U2 e C5 sono ancora su BAT
  • ❌ Non esiste in libreria un vero componente "solo piazzole nude da saldare" a 2 pad, quindi ho dovuto usare il sostituto piu' vicino disponibile
Next steps Posso completare io anche la parte finale: spostare U2 e C5 su BAT_SW per far funzionare davvero l'interruttore generale, poi fare un nuovo controllo mirato delle violazioni residue.
