Maduino Lora Radio (868M) Module 

Maduino Lora Radio (868M) is a main board based on the ATmega328 and RFM95W 868MHz module.

The LoRa Radio allows the user to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption. We use the Arduino pro mini 3.3V 8MHz bootloader in this board and use the CP2104 as USB to serial to upload the code by Arduino IDE.
