# ST B-L072Z-LRWAN1 - Cayenne GNSS Example
|

|
||||
This example demonstrates sending GNSS data in [CayenneLPP](https://developers.mydevices.com/cayenne/docs/lora/#lora-cayenne-low-power-payload) format, using a B-L072Z-LRWAN1 development board with a X-NUCLEO-GNSS1A1 expansion shield, to the myDevices Cayenne dashboard. For more information on adding your device to the Helium network, visit our quickstart guide [here](https://developer.helium.com/console/quickstart).
