Arduino Nano and LoRa RA-02 Request

flux

I can’t make changes in the project right now because execution credits are unavailable.
Current project state:
  • No components have been added yet.
  • No schematic wiring has been done.
  • The project is still empty.
Requested parts to add next:
  • Arduino Nano
  • LoRa RA-02 module, likely Ai-Thinker SX1278 RA-02
What remains to do when credits are available:
  1. Add Arduino Nano module to the schematic.
  2. Add RA-02 LoRa module.
  3. Wire RA-02 to Arduino Nano over SPI:
    • VCC to 3.3 V only
    • GND to GND
    • SCK, MISO, MOSI, NSS/CS
    • RESET
    • DIO0, optionally DIO1/DIO2
  4. Add required decoupling capacitors near the RA-02 power pins.
  5. Add level shifting if using a 5 V Arduino Nano, because RA-02 is not 5 V tolerant.
  6. Run schematic review and fix any issues.
Important note: the RA-02 LoRa module must be powered and signaled at 3.3 V. A standard 5 V Arduino Nano cannot connect directly to RA-02 logic pins without level shifting.
