Power supply:
Use the XIAO USB connector as power supply. The XIAO regulates the voltage down to 3.3v for the RFM module.
At the bottom of the PCB are extra connections for powering sensors or other modules.
The RFM only works on 3.3 volt. Higher voltage will damage your LoRa module!!
Connections:
The PCB makes all the necessary connections from the XIAO to the RFM module.
MISO, MOSI and SCK are connected to the standard pins.
The only thing you need to change in your sketch are the DIO and the NSS pins
| RFM | XIAO |
| DIO0 | A2 |
| DIO1 | Jumper X-3 to A3 |
| DIO2 | Jumper X-3 to A3 |
| NSS | A1 |
| MOSI | A10 |
| MISO | A9 |
| SCK | A8 |
| RST | Jumper X-0 to A0 |
This board is tested with the following libraries:
