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).

- A generic fixed resistor ideal for rapid circuit topology development. Its footprint automatically adapts based on the selected package case code—supporting 0402, 0603, 0805, 1203, and many other standard SMD packages, as well as axial horizontal and vertical configurations. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
