Pin Definitions, Dimension and Schematic

Pin Definition

Atmega328 D13-D11 SPI D10 D9 D8 D7 D6 D2
Function D13-D11 SPI SX1278 CS SX1278 RST SPI Flash CS LED Battery Check SX1278 IRQ

Loraduino

  • Demo sketch please find at, RF95 client send is default flashed in board - https://github.com/Edragon/Arduino/tree/master/Sketchbook/02_LORA
  • 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.
  • Sketch include battery check function, but not yet fine tuned (to-do)



Code

  • Demo Sketch - Use Radiohead RF95 library, preload demo sketch rf95_reliable_client

Set Frequency

...
  if (!manager.init())
   Serial.println("init failed");
 driver.setFrequency(470.0);   // add frequency set here
...


Updates and FAQ

R1.2 Version

Change SPI Flash from 16MBit to 8Mbit. Add LGT Version, use LGT logicgreen version 8F328 IC. Tested fully compatible!


Common Questions

  • No need to add any new board, just use "arduino pro mini - 3.3V/8M" as board when upload new code in arduino IDE
  • 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)
