The RFM95W transceivers feature the LoRaTM long-range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. Using Hope RF’s patented LoRaTM modulation technique RFM95W can achieve a sensitivity of over -148dBm using a low-cost crystal and bill of materials.
The high sensitivity combined with the integrated +20 dBm power amplifier yields an industry-leading link budget making it optimal for any application requiring range or robustness. LoRaTM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity, and energy consumption.

Worked as Intended. For those asking for Range,
This module, as all Lo-Ra modules give range depending on their Bandwidth allotment, More bandwidth= Less Sentitivity= Less Range.
My personal best with 2-3 Tests repeatability was beyond 13kms with 10mW Transmission power, this unit is capable of 100mW. measured is 88mW.
All in all, it has limited open library documentation available, but the hardware is straight-forward to use.
Works with ExpressLRS DIY builds.
Thanks Robu.in for stocking this unit.
