Highly recommended !
For SX1278 LoRa 433MHz Ra-02 Breakout Board 2PCS
Very good performing and inexpensive solution to discover the “magic” of Lora.
The products are sent very quickly and the communication with the vendor is perfect !
Be careful to test the modules : they are 3.3V logic level and so, using 2X Arduino Uno, is dangerous because they are 5V logic level !
Hence I used 2X Teensy 3.2 and adapt the rf95_Client and rf95_Server samples of the last Radio Head Library (https://www.airspayce.com/mikem/arduino/RadioHead/), using the samples of programs here proposed (Transmitter and Receiver) : all is ok then !
