== Loraduino ==<br />
* Demo sketch please find at, RF95 client send is default flashed in board - https://github.com/Edragon/Arduino/tree/master/Sketchbook/02_LORA<br />
* if you have a pair, just flash another one to client server, LED will blink when data is transceiving between two modules, and 9600 baudrate serial output hello to you.<br />
* Sketch include battery check function, but not yet fine tuned (to-do)<br />
<br />
<br />
<br />
<br />
== Code ==<br />
* Demo Sketch - Use Radiohead RF95 library, preload demo sketch rf95_reliable_client<br />
<br />
Set Frequency<br />
...<br />
if (!manager.init())<br />
Serial.println("init failed");<br />
driver.setFrequency(470.0); // add frequency set here<br />
...<br />
<br />
* [[Low_Power|Further low power test could see here]]. and [[https://b.electrodragon.com/t/9 thread on forum.]]<br />
<br />
<br />
== Updates and FAQ == <br />
<br />
=== R1.2 Version ===<br />
Change SPI Flash from 16MBit to 8Mbit.<br />
Add LGT Version, use LGT logicgreen version 8F328 IC. Tested fully compatible!<br />
<br />
<br />
<br />
=== Common Questions ===<br />
* No need to add any new board, just use '''"arduino pro mini - 3.3V/8M"''' as board when upload new code in arduino IDE<br />
* If any failed on programming please try to use 5V for power supply to 3.3V (which actually is VCC for SOC atmega328P, it is 3.3-5V tolerant)<br />
