 This repository contains the latest firmware for the SparkFun IoT Node - LoRaWAN development board. While the IoT Node - LoRaWAN development board is programmable using Arduino, the IoT Node - LoRa board ships with a firmware application that enables rapid sensor definition and deployment on a Digi LoRaWAN XON network. This repository contains the source for this LoRaWAN application and well as firmware releases.
