Arduino LoRa

An Arduino library for sending and receiving data using LoRa radios.

Compatible Hardware

• Semtech SX1276/77/78/79 based boards including:
  • Dragino Lora Shield
  • HopeRF RFM95W, RFM96W, and RFM98W
  • Modtronix inAir4, inAir9, and inAir9B

Semtech SX1276/77/78/79	Arduino
VCC	3.3V
GND	GND
SCK	SCK
MISO	MISO
MOSI	MOSI
NSS	10
NRESET	9
DIO0	2

NSS, NRESET, and DIO0 pins can be changed by using LoRa.setPins(ss, reset, dio0). DIO0 pin is optional, it is only needed for receive callback mode. If DIO0 pin is used, it must be interrupt capable via attachInterrupt(...).
