# Sparkfun Pro RF - Basic LongFi Example
|
||||
|
||||
This example demonstrates sending a simple data packet using a Sparkfun Pro RF development board. Visit our quickstart guide [here](https://developer.helium.com/devices/arduino-quickstart/sparkfun-pro-rf).
|
||||
|
||||
## 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.
|
||||
|
||||
[IBM LMIC framework](https://github.com/matthijskooijman/arduino-lmic)
|
||||
|
||||
## Required Arduino Board Support
|
||||
|
||||
### Arduino SAMD Boards (32-bits ARM Cortex-M0+) + SparkFun SAMD Boards
|
||||
Install board support packages, find instructions [here](https://learn.sparkfun.com/tutorials/sparkfun-samd21-pro-rf-hookup-guide?_ga=2.148378999.1172134851.1586114454-289367592.1582349414&_gac=1.242421430.1585837307.EAIaIQobChMI86GEgfjJ6AIVBQF9Ch0mpwyeEAEYASAAEgLFn_D_BwE#setting-up-arduino).
