RFM95W 433MHz LoRa Radio description:

The LoRa radios are exciting, longer-range and more powerful but also more expensive.

RFM95 @ 433 MHz – LoRa capable radio at 433 MHz for use in Europe ITU 1 license-free ISM, or for amateur use with restrictions (check your local amateur regulations!)

RFM95W 433MHz LoRa Radio:

this is the LoRa 9x @ 433 MHz radio version – the exact radio frequency is determined when you load the software since it can be tuned around dynamically. These are + 20dBm LoRa packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweakings

SX127x LoRa® based module with SPI interface
Packet radio with ready-to-go Arduino libraries
Uses the license-free ISM bands
+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.
Our initial tests with default library settings: over 1.2mi / 2Km line-of-sight with wire quarter-wave antennas. (With setting tweaking and directional antennas, 20Km is possible).
