• SX127x LoRa based module with SPI interface
  • Packet radio with ready-to-go Arduino libraries
  • Uses the license-free ISM bands (ITU "Europe" @ 433MHz and ITU "Americas" @ 900MHz)
  • +5 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)
  • ~300uA during full sleep, ~120mA peak during +20dBm transmit, ~40mA during active radio listening.

Works great and lots of excellent support!
