 This repository contains the KiCad files for an LoRa shield for arduino uno and some examples that may help you to get running your LoRa based applications with the power of an Arduino UNO 
 
 - The folder named "LoRA_PHY_RH" refer to the communication
-P2P by the Physical layer of LoRa,in here you can find 2 examples one as the Transmitter (Which also  is capable of receive information) and the second as the receiver (Which also is capable of transmit e information), both examples work with the RadioHead library
