Thought for a moment

Rozumiem, ale żebym mógł napisać “według datasheetu” MUSZĘ mieć dostęp do oficjalnego PDF dla Ra-01SH. W wynikach widzę stronę JLC/LCSC z linkiem do PDF (C2764087), ale nie mam bezpośredniego URL do pliku. Podeślij proszę bezpośredni link do PDF (np. z JLC/LCSC), a natychmiast wyciągnę dokładne fragmenty i przytoczę je dosłownie.
Równolegle, żebyś mógł kontynuować okablowanie już teraz, poniżej masz gotowy, praktyczny plan przypięć (wybór GPIO po Twojej stronie możesz zmienić; to nie są “cytaty z datasheetu”, tylko bezpieczny schemat połączeń, zgodny z najlepszymi praktykami):
  • RESET modułu -> IO12, net: RA01_RESET
    • Dodaj pull‑up 10 kΩ do 3V3 na linii RESET (zgodnie z zasadą: reset pin powinien mieć podciągnięcie).
  • BUSY modułu -> IO41, net: RA01_BUSY
    • Jako wejście MCU (wykorzystywane przez sterownik do czekania aż radio nie będzie zajęte).
  • DIO1 modułu -> IO42, net: RA01_DIO1
    • Wejście przerwaniowe MCU.
  • DIO2 modułu -> IO11, net: RA01_DIO2
  • DIO3 modułu -> IO13, net: RA01_DIO3
Przypomnienie dla linii SPI1 (które już prowadzisz):
  • SCK -> IO36 (SPI1_SCLK) przez 22 Ω
  • MOSI -> IO35 (SPI1_MOSI) przez 22 Ω
  • MISO -> IO37 (SPI1_MISO) przez 22 Ω
  • NSS/CS -> IO38 (SPI1_CS0)
  • Zasilanie: VCC -> 3V3, GND -> GND
Co potwierdzę z datasheetem, gdy tylko dostanę PDF:
  • Czy RESET jest aktywny w stanie niskim (typowo tak) i czy producent zaleca konkretną wartość podciągu/RC.
  • Czy BUSY musi być obowiązkowo podłączone (w SX126x tak) oraz poziomy logiczne/czasówki.
  • Jakie DIO są faktycznie wyprowadzone (często DIO1/DIO2/DIO3) i zalecenia dotyczące ich użycia/przerwań.
  • Ewentualne dodatkowe piny sterujące (TXEN/RXEN) oraz wymagane kondensatory odsprzęgające zasilanie modułu.
Podsumowując: podłączyć możesz od razu jak powyżej. Podeślij proszę link do PDF, a ja uzupełnię odpowiedź o dokładne brzmienie i numery pinów “według datasheetu” oraz doprecyzuję wymagane elementy pomocnicze (jeśli datasheet je zaleca).
