      2    RadioLib Si443x Settings Example
      3 
      4    This example shows how to change all the properties of RF69 radio.
      5    RadioLib currently supports the following settings:
      6     - pins (SPI slave select, nIRQ, shutdown)
      7     - carrier frequency
      8     - bit rate
      9     - receiver bandwidth
     10     - frequency deviation
     11     - output power during transmission
     12     - sync word
     13 
     14    For default module settings, see the wiki page

     16
