LoRa frequency must match the geographic region the device is operated in.
Running it with the incorrect frequency most likely violates the law.

The chip type used for LoRa radio.
Most boards use the SX1276 .. SX1279 chips. This includes ttgo LoRa and HopeRF RFM95 boards.
Earlier boards might use the SX1272 / 73 chips, e.g. the HopeRF RFM92.

Reset pin can be floating for most boards and shields.
A few boards/shields require the pin to be held high for operation.

Priority of task running in the background and communicating with
the LoRaWAN radio chip. It needs a high priority as the timing is crucial.
Higher numbers indicate higher priority.
