This is a LoRa wireless transceiver module based on SEMTECH's original SX1276 chip.   

It can operate in the 900 to 931 Mhz band.    

This is the fastest and easiest way to implement LoRa technology in your projects because the module   

connects via standard TTL serial port. You can make transparent serial communication between   

devices.    

LoRa technology is ideal for IoT applications as it transmits over long distances with low power consumption.   

very low energy.   

The module can be used with the default configuration, but if you need   

change it, below we leave you the download link for the free configuration software.   

To configure the module you can use a common USB to TTL converter,   

such as  this one   or  this one   or you can even use an Arduino board. 

As indicated in the manual, to enter the configuration mode the M0 and M1 pins must be   

in high level (3.3V or 5V), which is Sleep mode.
