This is the radio with the best range performance, thanks to the excellent receiver sensitivity that the LoRa™ technology offers.
Besides, Libelium has developed a library which enables addressable, reliable and robust communications with ACK, re-tries or
time-outs strategies.
The user can set any frequency in the 868 and 900MHz bands, with pre-defined channels. The use of this module is allowed in
virtually any country.
