Tak - i już widać dlaczego.
W Twoim schemacie net GND nie jest tylko masą, tylko zawiera też zwykłe sygnały, więc wszystkie pady należące do tego netu będą na PCB zachowywać się jak masa.
Najgorsze przykłady:
Czyli problem nie jest w samych padach - pady są poprawne, ale należą do złego netu.
Co zrobić:
  • Usuń błędne połączenia z netu GND dla pinów sygnałowych.
  • Zostaw w GND tylko prawdziwą masę, np. U4, M2, DS1, GND1.
  • Piny sygnałowe zrób na osobnych netach:
    • M2 -> osobny net do odpowiedniego GPIO
    • M2 -> osobny net
    • M2 -> do GND albo 3V3 tylko jeśli celowo wybierasz kanał
    • U4, U4, U4, U4 nie mogą być w masie, jeśli mają być używane jako sygnały.
Najpewniej stało się jedno z tych:
  • przewód został przypadkiem dotknięty do portalu masy GND1,
  • kilka przewodów dostało tę samą nazwę netu,
  • któryś pin został fizycznie połączony jednym ciągłym wire z masą.
Jeśli chcesz, mogę Ci teraz wypisać dokładnie które piny trzeba odłączyć od GND i do czego je podłączyć.
