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.

Replace with wire pads

Check battery connector refs

Use SW2 wire pads
