Podsumowanie przepływu połączeń (obserwowalne fakty)
  • Zasilania i masy:
    • Sieć GND łączy m.in. C1 (obie elektrody), C2:P2, R3:~, C9:K, Q6:DRAIN i GATE, D1:- , R4:P2, SPK1:-, [Audio Module](Audio Module):6, C3:P1, BATT2:-, C5:K.
    • U2:VO jest na Net 30 (wspólny z U1:AVCC oraz Q4:E).
    • U1:VCC jest na Net 21 (z OLED1:5V i [Audio Module](Audio Module):3). U1:GND jest na Net 27.
  • Interfejsy/połączenia logiczne:
    • Linie OLED1:SCL i SDA są odpowiednio na Net 19 (z U1:PC5) i Net 20 (z U1:PC4).
    • U1:PC0 i PC1 są połączone z [Audio Module](Audio Module) (Net 23 i Net 22).
  • Transformator i mostek:
    • T1:S1 -> D1:P3 (Net 18); T1:S2 -> D1:P2 (Net 24); D1:+ -> Net 32 (m.in. R13:P1, C11:P1); D1:- -> GND.
  • Zespół MOSFET + dławik:
    • Q7:DRAIN z L1:P1 (Net 34); Q7:SOURCE z C11:P2 (Net 1).
    • Q8:DRAIN z R13:P2 (Net 31); Q8:SOURCE z L1:P2 (Net 35).
    • Bramy Q7 i Q8 są na Net 33 (z R14:P1).
  • Głośnik i kondensatory:
    • SPK1:+ z C6:K (Net 16); C6:A jest w Net 13 wraz z C7:P1 i C8:P2. SPK1:- do GND.
  • BJT i sterowanie:
    • Q1:B z R2:P1 (Net 6), Q1:C z T1:P1 i R1:P2 (Net 2), Q1:E na Net 27.
    • Q2:B z R1:P1 (Net 5), Q2:C z T1:P2 i R2:P2 (Net 3), Q2:E na Net 27.
    • Q3:E z R12:P1 (Net 29); Q3:B i C są na Net 27.
    • Q4:B na Net 25, Q4:C na Net 26, Q4:E na Net 30.

  • Baterie i kondensatory przy zasilaniu:
    • BATT2:+ na Net 7 (z C2:P1, C5:A, C3:P2), BATT2:- na GND.
    • BATT1:+ i BATT1:- są na Net 27 (razem z wieloma innymi węzłami – patrz tabela).
  • Regulator i inne elementy:
    • U2:VI na Net 28 (z R10:P2), U2:VO na Net 30, U2:GND na Net 25.
    • R14:P2 z U1:PB3 (Net 36).
Obserwacje (tylko to, co bezpośrednio wynika z połączeń)
  • Zgodnie z netlistą BATT1 ma zaciski + i - połączone w tej samej sieci (Net 27).
  • C1 ma obie okładki do GND.
  • Bramka i dren Q6 są do GND; źródło Q6 jest w Net 35.
  • Wyjście U2:VO (Net 30) nie jest na tej samej sieci co U1:VCC (Net 21) – są to dwie różne sieci zasilające w obecnej topologii.
  • W BOM widnieje pozycja LM386 bez przypisanego oznaczenia; nie występuje w powyższych połączeniach sieciowych (nie został powiązany z żadną siecią).
Jeśli chcesz, mogę:
  • Wygenerować czytelny diagram blokowy przepływu sygnałów/zasilania według obecnych sieci.
  • Przejrzeć pod kątem typowych problemów (np. pętle masy, brakujące rozdzielenie zasilania analog/cyfra) i wypunktować wyłącznie obserwowalne nieścisłości.
  • Dodać/uzupełnić oznaczenia i opisy elementów oraz wartości pasywów, by ułatwić dalszy przegląd.
