# ST B-L072Z-LRWAN1 - 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). For more information on adding your device to myDevices Cayenne, visit our guide [here](https://developer.helium.com/console/integrations/mydevices-cayenne-integration).

|
||||
## Required Arduino Libraries
|
||||
|
||||
From the Arduino IDE, open the Library Manager (Sketch->Include Library->Manage Libraries). In the search box, type the library name below and install the latest version.
|
||||
|
||||
[MCCI Arduino LoRaWAN Library](https://github.com/mcci-catena/arduino-lmic)
