   RFM95: New Long Range Radio Module By Adafriut

   Introduction

   The conception is a quite simple: Managing Microcontroller and a highly-integrated radio module with incorporated USB battery charging circuitry, inserted together at one PCB Board.

   The module is perfectly suited for making any kind of the wireless networks with not as higher as Wifi Power Requirements, but with concurrent to BLE Hardware & profile versatility.
