Overview

This product is a transmitter / receiver RF LoRa configured to operate at a frequency of 433MHz. 

LoRa is a protocol for transmitting data emerged in recent years that wishes to contribute to the needs of users to transmit data at distances increasingly larger with very low energy consumption.

Communication can be made between transceivers (point - to - point) or by connecting to a router LoRa in coverage areas. The emergence of the protocol will help LoRa v2 and location through triangulation.
